Area codes
US area codes that are running out.
NANPA’s April 2026 forecast puts 10 of the 239 US area-code regions at exhaust before 2030 and 34 before 2035. The soonest are 347/718/917/929 in New York (Q3 2027) and 657/714 in California (Q2 2028). Every region is listed below with what NANPA’s own records say is being done about it.
- 10 regions before 2030
- 34 before 2035
- Next forecast October 2026
The next ten years
The 25 regions projected to run out first
A region is one area code or one overlay group: codes that cover the same ground draw on one pool of prefixes, so NANPA forecasts them together. “Projected exhaust” is the quarter in which NANPA expects the last prefix to be assigned. The last column is what NANPA’s code report of October 19, 2026 records for the region: a new code already assigned, relief planning in progress, or nothing yet.

What is already being done
New codes assigned, and regions in planning
NANPA assigns a new code once a state commission has approved a relief plan. Three codes are assigned and waiting to go into service, and 6 more regions have relief planning under way without a code assigned yet.
- 01565 for 912 (Georgia)912 is projected to exhaust in Q2 2028. 565 goes into service on 6 Dec 2027.
- 02761 for 502 (Kentucky)502 is projected to exhaust in Q1 2029. 761 was assigned on 7 Aug 2025; the in-service date is not yet set.
- 03451 for 828 (North Carolina)828 is projected to exhaust in Q2 2029. 451 was assigned on 15 Sep 2026; the in-service date is not yet set.
Relief planning in progress, no new code assigned yet: 657/714 (California, Q2 2028), 956 (Texas, Q2 2029), 949 (California, Q3 2029), 580 (Oklahoma, Q3 2029), 509 (Washington, Q3 2029), 626 (California, Q1 2030).
Since October 2025
How the forecast moved
Of the regions with a comparable figure, 183 moved later, 41 moved earlier and 5 did not move. Big jumps outward usually mean a new code went into service; jumps inward mean carriers now expect to need more prefixes.

How NANPA forecasts exhaust
- Prefixes are the unitAn area code holds 792 usable prefixes, the three digits after the area code, and each prefix is 10,000 numbers. A code is “exhausted” when no prefix is left to assign, whatever the state of individual numbers.
- Carriers report twice a yearEvery carrier that holds numbers files a utilization and five-year forecast report with NANPA, due 1 February and 1 August. NANPA combines those forecasts with its own record of monthly prefix assignments.
- The forecast is published in April and OctoberThis page uses the April 2026 analysis, built on data as of March 1, 2026. Anything that happened after that date, including codes that went into service in the summer of 2026, is not in it; the relief column comes from NANPA’s code report of October 19, 2026.
- Relief starts three years outWhen a code is within 36 months of running out, NANPA notifies the state regulator and the carriers, the industry agrees a plan, and the state commission decides. Nearly every recent decision has been an overlay: a second code on the same map, with ten-digit dialling.
If it is your code
What happens when your area code runs out
- 01Your number does not changeRelief is almost always an overlay now. Existing numbers keep their code; the new code is issued to new lines once the old one is nearly full.
- 02Dialling changes onceAn overlay cannot start until every local call is dialled with the area code. If your region still dials seven digits, that is the change you will notice, and it happens before the new code appears.
- 03Equipment that stores numbers needs checkingAlarm panels, fax machines, call forwarding rules and speed dials set up with seven digits stop working on the mandatory date. Planning letters publish a test number in the new code before it goes live.
FAQ
Area codes running out: FAQ
Which US area codes are running out soonest?
On NANPA’s April 2026 forecast: 347/718/917/929 (New York, Q3 2027), 657/714 (California, Q2 2028), 912 (Georgia, Q2 2028), 502 (Kentucky, Q1 2029), 828 (North Carolina, Q2 2029), 956 (Texas, Q2 2029). Each already has relief under way or a new code assigned, apart from the ones marked with a dash in the table.
How many area codes will run out before 2030?
10 of the 239 US area-code regions are projected to exhaust before 2030, 34 before 2035 and 57 before 2040. A region is one code or one overlay group, since codes that share an area share their supply.
What happens when an area code runs out?
A new code is added. NANPA notifies the state regulator about three years before the projected date, the carriers agree a plan, and the state commission decides whether to overlay a new code on the same area or split the map. Overlays are the norm now: nobody’s number changes, and every local call is dialled with the area code.
Will the United States run out of area codes altogether?
Not soon. Of the 800 possible codes, NANPA counts 649 usable for geographic areas across the whole numbering plan. On its April 2026 model, with demand of about 4,336 prefixes a year, the plan as a whole lasts until 2060; with demand 12.5% lower, until 2065. Demand has fallen each year since 2023.
Why did some forecasts move by decades?
Two reasons. A new code went into service and the region’s supply jumped: Alabama’s 334 moved from 2026 to 2064 when 483 was added. Or demand changed: Minnesota’s 763 moved earlier by 131 quarters because carriers now expect to need more prefixes there. NANPA marks each row with the reason.
Why does the New York 718 group show 2027 when a new code was just added?
Because the April 2026 forecast uses data as of March 1, 2026, and 465 went into service on 18 June 2026. The October 2026 forecast will show the effect. The relief column on this page already notes 465 from NANPA’s code report.
Does my phone number change when my area code runs out?
No. Under an overlay, which is how relief has been done in nearly every recent case, existing numbers keep their area code. The only change is dialling the area code on every call, if your region does not already.
How often is this page updated?
When NANPA publishes a new forecast, in April and October, and the data module behind the tables is regenerated from the published files. The next analysis is due in October 2026.
