Frequently asked about 509

What state is area code 509?

Washington.

Can I still get a 509 number?

Only from recycled stock. 763 of the 786 available blocks are already allocated, so new numbers in the area normally come from a newer code.

Is a call from 509 a scam?

Not by itself. 509 drew 371 FTC complaints in the 33 days to 30 October 2026, 263rd of 422 ranked codes – mid-pack or lower. Spam callers spoof caller IDs, so the only useful check is the full number.

Which carrier owns 509 numbers?

Lumen / CenturyLink holds the largest share of assigned number blocks at 31.8%. The rest is spread across 3 other carriers. This is share of number blocks, not of subscribers – people keep their numbers when they switch carriers.

Do I need to dial 10 digits in 509?

Yes – ten digits for local calls in 509, because it shares its area with another code.

Is a new area code coming to the 509 area?
