Is June 30, 2026 the date all AT&T copper lines shut off?

No. June 30, 2026 is the start of one approved shutdown wave, not a nationwide cutoff for every remaining AT&T legacy line.

Who is affected by the AT&T copper shutdown?

Businesses and households still using older AT&T landline-style service can be affected, especially if the line still powers a main business number, fax, alarm, gate, elevator, or medical-monitor device.

What happens if I do nothing after receiving an AT&T notice?

AT&T says affected customers should make arrangements by the deadline in the notice. If you do nothing, the legacy service can be disconnected after that date.

Can I keep my AT&T phone number?

Yes. If the number is important to your business, keep the AT&T line active, sign up for Phone2, choose a temporary number, and submit the port request before canceling anything.

How long does it take to port an AT&T number to Phone2?

Some ports finish in a few business days, but older landline and more complex cases can take longer. Start early and keep the existing AT&T line active until the port completes.
