Area code 253: where it is and who calls from it

  • PT (UTC−8/−7)

What is area code 253?

Area code 253 serves Washington, United States. It is in the PT (UTC−8/−7) time zone.
Where area code 253 sits in a North American number: the three-digit area code, then the three-digit exchange code, then the four-digit line number, all under country code 1. The diagram also shows the two validity rules — an area code never starts with 0 or 1, and a repeated middle digit marks a service code such as 800 for toll-free rather than a place.
The 1 you dial before a ten-digit number is a long-distance prefix, not part of the number itself.

Step by step

How to call a 253 number

The same ten digits, dialled three different ways depending on where you are calling from.

  1. 1

    Within the same area code

    Many carriers still allow seven digits inside 253, but overlays have made ten-digit dialling the safe default. Dial 253 followed by the seven-digit number.
  2. 2

    From elsewhere in the US or Canada

    Dial 1, then 253, then the seven-digit number — eleven digits in total. The leading 1 is the North American long-distance prefix, not part of the number.
  3. 3

    From outside North America

    Dial your country's exit code, then 1 for the North American Numbering Plan, then 253, then the seven-digit number. On a mobile, type + instead of the exit code: +1 253 followed by the number works from any country.

Background

About 253

253 covers Washington with no overlay code sharing its territory, so the code still maps cleanly to one place — which is what makes it recognisable on caller ID. It entered service in 1997, carved out as the numbering plan was expanded to keep up with demand for numbers.

Unwanted calls

Why you are getting 253 calls

The reason an unfamiliar 253 number keeps calling is usually neighbour spoofing: automated systems fake a caller ID in the recipient’s own area code because a local-looking number is answered far more often than an unfamiliar one. The number displayed is frequently not the number placing the call, and may belong to someone with no idea it is being used.

What actually helps:

  • Let unknown numbers go to voicemail. Automated diallers rarely leave a message; a real caller will.
  • Do not press any key to be removed. On an automated call, a keypress confirms a live human and increases the volume you get.
  • Register on the national Do Not Call list and report unwanted calls. It does not stop fraud, but it does constrain legitimate telemarketers.
  • Turn on your carrier’s call-filtering service. Filtering now uses STIR/SHAKEN attestation, which is why properly signed business calls get through and spoofed ones increasingly do not.

If it is your 253 business number being labelled as spam, the cause is different and fixable: unregistered caller ID name, low attestation, or a volume pattern carriers read as automated. Owning your numbers, registering CNAM and signing at Attestation A is what resolves it.

If you are calling into 253 rather than receiving from it, the relevant reading is putting your business name on the call — the same signals that decide whether a call from this code gets answered decide whether yours does.

Frequently asked questions

Where is area code 253?
Area code 253 covers Washington, United States.
Is a call from 253 a scam?
Not inherently. 253 is a legitimate area code serving real people and businesses in Washington. But spam callers frequently spoof caller ID to display a number in your own area code, a technique called neighbour spoofing. If you do not recognise the number, let it go to voicemail; a genuine caller will leave a message.
What time zone is 253 in?
253 is in the PT (UTC−8/−7) time zone. Check the local time before calling back so you are inside normal business hours.
Can I get a 253 phone number?
Yes. Local numbers in 253 can be provisioned in minutes and used for calls, texts, and as your outbound caller ID. A number in the area code you are calling is answered noticeably more often than an out-of-state one.
