0204 London area code

Who Called Me From a 0204 Number? London Area Code Lookup

A 0204 number is a London geographic landline number. Ofcom began allocating 0204 numbers from 2018 onwards as the original 020 ranges (0207 / 0208 / 0203) ran out of capacity. Functionally a 0204 number is no different from a 0207 / 0208 / 0203 number — same London area code (020), same call cost, same dialling rules.

Risk: Low — 0204 numbers are London geographic landlines. They are charged at the standard local-rate (typically included in inclusive call plans) and are not premium-rate.

Frequently asked questions about 0204 numbers

What is the 0204 area code?

0204 is part of the London 020 area code — Ofcom opened the 0204 range from 2018 to provide additional capacity as the original 0203 / 0207 / 0208 ranges filled up. A 0204 number is geographically a London number and is dialled as 020 4XXX XXXX or 0204 XXX XXXX (both forms are correct).

Who called me from a 0204 number?

A 0204 caller is using a London landline. Type the full 11-digit 0204 number into the free checker on this page to see which UK communications provider Ofcom originally allocated that specific block to (BT, Gamma, Vodafone, Sky, Virtual1 and others all operate within the 0204 ranges).

Is 0204 the same as 020?

Yes. 0204 is a sub-range of the 020 area code. The full London area code is 020, and 0204 is one of four overlays (0203, 0204, 0207, 0208) that Ofcom has opened over time to provide enough number capacity for London. They share the same call-cost rules.

How much does it cost to call 0204?

Calling a 0204 number costs the standard geographic landline rate from any UK provider — included in inclusive call minutes on every modern landline and mobile plan. It is not a premium-rate, freephone or service number.

Why am I getting calls from 0204?

Many UK businesses pick 0204 numbers for new London phone lines because the 0207 / 0208 / 0203 ranges are largely exhausted. Sales-call centres, telemarketers and legitimate London businesses all use 0204 numbers. If a 0204 call is unsolicited and unwanted, register with the Telephone Preference Service (TPS) at tpsonline.org.uk to block sales calls.
