Where is the 01603 area code?

The 01603 dialling code is the UK geographic area code for Norwich, covering Norwich and the surrounding Norfolk area. Norwich lies in Norfolk, in the East of England region of England. Norwich is a fine medieval city and the regional capital of Norfolk, a UNESCO City of Literature.

Because 01603 is a geographic (01/02) code, a number using it is tied to the Norwich area — though with modern hosted telephony (VoIP) a business can keep an 01603 number even after moving premises, so the code reflects the original area rather than a guaranteed physical location today.

Norwich phone number format & example

An Norwich number is made up of a 5-digit area code followed by a 5 or 6-digit local number. Written in full it looks like 01603 XXXXXX (the Xs stand for the local digits). Ofcom has not reserved a dedicated fictitious range for 01603. For on-screen examples it recommends the unused 01632 96000001632 960999 range. Real Norwich numbers follow the pattern 01603 XXXXXX.

How to dial a Norwich (01603) number

  • Within the Norwich area: on most lines you can dial just the local part of the number, although dialling the full national number including 01603 always works.
  • From elsewhere in the UK: dial the full number including the area code — 01603 XXXXXX.
  • From abroad: replace the leading 0 with +44+44 1603 XXXXXX.

Call charges for 01603 numbers

Calls to 01603 geographic numbers are charged at your phone provider’s standard UK landline rate and are normally included in any inclusive call minutes on your landline or mobile plan. UK-wide 03 numbers are guaranteed by Ofcom to cost the same as 01/02 calls, while 084, 087 and 09 numbers cost considerably more — so it’s always worth checking the prefix before you dial.

Spotting spoofed 01603 scam calls

Fraudsters frequently spoof local dialling codes, faking the caller ID so a scam call appears to come from a nearby Norwich (01603) number you might trust. This is called neighbour spoofing. Remember:

  • A familiar 01603 area code is not proof the caller is local or genuine — caller ID can be faked.
  • Banks, HMRC and the police will never ask you to move money or share passwords or one-time codes over the phone.
  • If a call feels off, hang up, wait a moment, and call the organisation back on a number from their official website or your statement.
  • Report nuisance calls to the ICO and forward scam texts to 7726 (free).
