Which States Still Require Certified Mail in 2026

Last reviewed: October 2026

This page is reviewed every January and again after any state legislative session that amends an eviction notice statute.

Some states still expressly name certified mail or registered mail as a required or preferred service method for eviction notices in 2026 (Ohio, Illinois, New York, and Iowa are the clearest examples) while other states, notably Washington after its 2026 law change to the unlawful detainer statute, now allow the notice to be sent through the mail without requiring Certified Mail. In most states, personal delivery, substituted service, or posting plus mailing is also allowed, and the safest practice is to use the method your statute names and keep proof of mailing.

This is a general informational guide, not legal advice. Eviction, unlawful detainer, notice, and service requirements can change quickly and may also depend on the type of tenancy, the reason for eviction, local court rules, and the facts of your case. Confirm the current requirements with your own attorney before serving a notice.

Which States Still Name Certified Mail in Their Eviction Notice Statutes?

The most important distinction is between a state that expressly names certified or registered mail as an authorized method and a state that requires certified mail as the only method.

The nine states below do not all treat certified mail the same way:

State	2026 Service Method Summary	Primary Citation
Ohio	Certified mail return receipt requested is one authorized method for the three-day notice. Personal delivery or leaving the notice at the usual place of abode or premises is also allowed.	Ohio Rev. Code § 1923.04
Illinois	Certified or registered mail with return receipt is an authorized method. Service by mail is effective when deposited, even if the tenant never claims it.	735 ILCS 5/9-104 and 735 ILCS 5/9-211
New York	After personal, substituted, or affixing service, the notice must also be mailed by registered or certified mail and by regular first-class mail.	RPAPL § 735
Iowa	Certified mail is an expressly named service method, and service is complete when the notice is mailed in a sealed, properly addressed envelope with postage.	Iowa Code § 562.7
Washington	After June 11, 2026, unlawful detainer notices covered by RCW 59.12.040 may be sent through the mail; Certified Mail is no longer required for this notice.	HB 2664, Ch. 144, Laws of 2026 (69th Leg., 2026 Reg. Sess.), approved Mar. 23, 2026, effective June 11, 2026, amending RCW 59.12.040
Texas	First-class, registered, certified mail, delivery service, posting inside the premises, hand delivery, or agreed electronic notice may be used.	Tex. Prop. Code § 24.005
Florida	Mailing, delivery of a true copy, permitted email, or leaving a copy at the residence may be used. Certified mail is not required.	Fla. Stat. §§ 83.56(4) and 83.57
California	Personal delivery, substituted delivery plus mailing, or posting plus mailing are named methods. Certified mail is not required.	Code Civ. Proc. §§ 1161 and 1162
Arizona	The cited statutes address written notice periods for month-to-month termination and nonpayment notices.	A.R.S. § 33-1375 and A.R.S. § 33-1368

This list is not exhaustive. Unlisted states should be checked against their current statutes, applicable court rules, and local requirements.

What Did Washington Change in 2026?

Washington is the headline change for landlords and property managers handling unlawful detainer notices.

HB 2664, Ch. 144, Laws of 2026 (69th Leg., 2026 Reg. Sess.), approved Mar. 23, 2026, effective June 11, 2026, amending RCW 59.12.040, removed the Certified Mail requirement from the unlawful detainer mailing language in RCW 59.12.040.

The enacted text deletes "by certified mail, posted from within Washington state, to the last known address of" and replaces it with "through the mail addressed to the person entitled thereto at the person's place of residence."

The service-completion language now states that service is complete "when such copy is deposited in the United States mail from within Washington state properly addressed with postage prepaid." The statute also retains the timing rule that "when service is made by mail five additional days shall be allowed before the commencement of an action based upon such notice."

That means Washington landlords using RCW 59.12.040 for unlawful detainer notices no longer must use Certified Mail for this notice as of June 11, 2026. The notice may be sent through the mail, while still following every other service, timing, and documentation requirement.

The change does not mean that every Washington landlord notice changed or can be sent casually. This amendment is to RCW 59.12.040 for unlawful detainer notices, not all notices under chapter 59.18 RCW. You still need to use the correct notice, address it properly, mail it from within Washington when required, account for the additional five days, and retain proof of what was mailed and when.

Which States Expressly Name Certified or Registered Mail?

What Does Ohio Require for a Three-Day Notice?

Under Ohio Rev. Code § 1923.04, before starting an eviction action for residential premises, the landlord must notify the tenant to leave at least three days before filing the action.

The notice may be served by:

• Certified Mail, Return Receipt Requested.
• Delivering a written copy in person.
• Leaving the notice at the defendant’s usual place of abode or at the premises.

The notice must also conspicuously include the statutory warning language:

“You are being asked to leave the premises. If you do not leave, an eviction action may be initiated against you…”

Ohio therefore expressly names certified mail, but certified mail is not the only authorized method listed in the statute.

How Does Illinois Treat Certified Mail?

Under 735 ILCS 5/9-104 and 735 ILCS 5/9-211, a demand for possession or notice may be served by:

• Delivering a copy to the tenant.
• Leaving it with someone age 13 or older on the premises.
• Sending it by certified or registered mail with a return receipt.
• Posting it when no one is in possession.

Service by certified or registered mail is effective upon deposit in the mail, even if the tenant never claims the letter. That makes the mailing record especially important when you are managing multiple properties or handling notices under strict deadlines.

Does New York Require Certified Mail?

Under RPAPL § 735, the notice of petition and petition in a summary proceeding must be served through one of the statute’s listed methods:

• Personal delivery.
• Substituted delivery to a person of suitable age and discretion.
• Affixing the papers to the property.

Within one day, the papers must then be mailed to the respondent by registered or certified mail and regular first-class mail. Service by mail is complete upon filing proof of service.

New York’s process is different from a simple “send the notice by certified mail” rule. The required service sequence and proof of service both matter.

What Are Iowa’s Certified Mail Rules?

Under Iowa Code § 562.4, thirty days’ written notice terminates a tenancy at will, although shorter intervals apply if rent is payable more often.

Under Iowa Code § 562.7, notice served by certified mail is complete when mailed in a sealed, properly addressed envelope with postage. For lease violations, Iowa Code § 562A.27 provides a seven-day cure notice, while nonpayment has a three-day notice period.

If you are serving Iowa notices by mail, keep the envelope details, mailing date, address, postage information, and any USPS receipt or tracking record with the case file.

Which States Name Other Service Methods?

How Does Texas Permit Eviction Notice Delivery?

Under Tex. Prop. Code § 24.005, at least three days’ written notice to vacate is required before a forcible detainer suit unless the lease says otherwise.

The notice may be delivered by:

1. First-Class, Registered, Certified Mail, or a delivery service.
2. Delivery to a conspicuous place inside the premises.
3. Hand delivery to any tenant age 16 or older.
4. Electronic notice if the parties agreed to it in writing.

Texas expressly includes certified mail, but it also names several other delivery options.

Is Certified Mail Required in Florida?

Under Fla. Stat. §§ 83.56(4) and 83.57, termination notices may be delivered by mailing, delivering a true copy, emailing in accordance with § 83.505, or leaving a copy at the residence if the tenant is absent.

Certified mail is not required under the cited provisions. Periodic tenancy notice periods run 60, 30, or 7 days depending on the tenancy type.

How Are California Three-Day Notices Served?

Under Code Civ. Proc. §§ 1161 and 1162, three-day notices to residential tenants may be served by:

• Personal delivery.
• Leaving the notice with a person of suitable age and discretion, followed by mailing a copy.
• Posting the notice conspicuously and mailing a copy when other methods fail.

California does not impose a certified mail requirement under the cited provisions. Still, property managers and law firms should keep evidence of the method used, the date, the address, and the mailed copy.

What Do the Arizona Statutes Address?

Under A.R.S. § 33-1375, month-to-month tenancies terminate on written notice given at least 30 days before the periodic rental date.

Under A.R.S. § 33-1368, a landlord may provide five days’ written notice for nonpayment before a special detainer action.

The cited Arizona provisions focus on written notice periods. They do not create a certified mail requirement in the facts covered by this guide. Confirm the current service procedure for your notice type with your attorney.

How Should You Serve a Three-Day or Pay-or-Quit Notice?

Start by identifying four things:

• The state where the property is located.
• The type of notice you are serving.
• The deadline before filing an eviction or unlawful detainer action.
• The service method authorized by the current statute.

Then follow the statute exactly. If certified or registered mail is named, using certified mail can create a clear mailing record and USPS certified mail tracking history. If personal delivery, substituted service, or posting plus mailing is required or permitted, document each step.

For property management companies, the practical challenge is often volume. You may be preparing dozens or hundreds of notices while tracking different dates, properties, tenants, and internal account numbers.

Here are just a few ways to make the process easier:

• You’ll create and print USPS certified mail labels online from a home or office printer.
• You’ll avoid a trip to the Post Office for each notice.
• You’ll receive a USPS tracking number for each certified mailing.
• You’ll have a centralized record of mailing and delivery activity.
• You’ll reduce manual data entry by uploading address lists.
• You’ll be able to use Excel or CSV batch processing for larger jobs.
• You’ll have options for API and SFTP automation for recurring high-volume workflows.
• No monthly fees, no contracts, no equipment leases, and no dedicated postage meter.
• You’ll keep important mailing records in a searchable compliance archive.

Learn how to create and print USPS Certified Mail Labels online when you want to prepare and mail letters yourself.

If you want to skip printing, folding, inserting, and mailing, use the Print & Mail full-service option. Upload a PDF letter and address list, and the service can print, insert, apply postage, and mail orders received before 5:00 PM Eastern the same business day. Mailings include USPS proof of acceptance, tracking, delivery information, and a notarized affidavit of mailing.

For recurring notice campaigns, review the Excel batch labels and API/SFTP automation options.

What Proof of Service Should You Keep?

Your file should show what was served, who was served, where it was sent or delivered, and when the service occurred. Depending on the statute and method, useful records may include:

• A copy of the exact notice.
• The tenant’s address and any internal property or account reference.
• The date the notice was prepared.
• The date it was mailed, posted, or delivered.
• The USPS receipt and tracking number.
• The USPS acceptance scan.
• Delivery confirmation or attempted-delivery information.
• A return receipt or electronic signature record when purchased.
• A certificate, affidavit, declaration, or other proof of service required by the applicable procedure.

Certified Mail Labels provides a searchable digital record of certified mail activity, including proof of mailing, USPS acceptance scans, tracking events, delivery confirmations, and signature records. The company’s Certified Mail reports support long-term recordkeeping through a 10-year compliance archive at no additional charge.

If you need signature evidence, the Electronic Return Receipt option is listed at $2.91, compared with $4.65 for the traditional paper green card. A $1.74 saving per piece. The electronic return receipt provides a PDF record of delivery.

Pricing can change, but one current comparison is a 1-ounce certified mail letter with Electronic Delivery Confirmation at $7.28 online, compared with $11.02 at the Post Office counter with a green card return receipt.

Frequently Asked Questions About Eviction Notice Certified Mail

Does Washington Still Require Certified Mail for Eviction Notices in 2026?

No. HB 2664, Ch. 144, Laws of 2026 (69th Leg., 2026 Reg. Sess.), approved Mar. 23, 2026, effective June 11, 2026, amending RCW 59.12.040 removed the Certified Mail requirement for unlawful detainer notices under RCW 59.12.040. The act deletes "by certified mail, posted from within Washington state, to the last known address of" and replaces it with "through the mail addressed to the person entitled thereto at the person's place of residence." Service is complete "when such copy is deposited in the United States mail from within Washington state properly addressed with postage prepaid," and "when service is made by mail five additional days shall be allowed before the commencement of an action based upon such notice."

Which States Require Certified Mail for a Three-Day Notice?

The clearest examples in this guide are Ohio, Illinois, New York, and Iowa, but the statutes do not all work the same way. Ohio expressly allows certified mail among several methods. Illinois allows certified or registered mail and treats mailing as effective upon deposit. New York requires registered or certified mail as part of its service sequence. Iowa expressly names certified mail for service.

Is Certified Mail Effective If the Tenant Never Picks It Up?

In Illinois, service by certified or registered mail is effective upon deposit in the mail even if the tenant never claims it under 735 ILCS 5/9-104 and 735 ILCS 5/9-211. Other states may use different rules. Do not assume that an unclaimed letter has the same legal effect everywhere.

How Much Time Does Certified Mail Add to an Eviction Timeline?

There is no single nationwide answer. Timing depends on the state, notice type, service method, and statute. Washington’s 2026 change specifically adds five days for the applicable mailed notice procedure. Confirm the filing timeline with an attorney before relying on any mailing date.

Can I Serve an Eviction Notice by Regular Mail?

Sometimes. Washington now allows unlawful detainer notices covered by RCW 59.12.040 to be sent through the mail after June 11, 2026. Texas, Florida, and other states also name mailing among available methods in the cited provisions. But regular mail is not automatically valid in every state or for every notice. Check the current statute for the property and notice type.

How Can I Send Certified Mail Without Going to the Post Office?

You can use a certified mail online platform to create postage-paid USPS certified mail labels, print certified mail online, apply the labels to your envelopes, and place the mail into the USPS system according to the service instructions. You can also upload a PDF and address list for a full-service print-and-mail workflow.
