Area Code 113: Leeds (UK), Not a US Area Code
There is no area code 113 in the US or Canada – North American area codes must start with a digit from 2 to 9. In the UK, 0113 (+44 113) is the area code for Leeds, England. A bare “113” is a short service number in some countries, such as the police in Italy.
Why 113 can't be a North American area code
The North American Numbering Plan (NANP) writes every number as NXX-NXX-XXXX, where N is any digit 2–9 and X is any digit 0–9. The digit 1 is reserved as the long-distance prefix (you dial 1 + area code + number), and 0 reaches the operator. An area code that started with 1 would clash with that prefix, so 1xx codes have never been assigned.
- When the NANP was created in 1947, 86 original area codes were assigned, all starting with 2–9.
- Codes of the form N11 (211, 311, 411, 511, 611, 711, 811, 911) are reserved for services, never used as area codes.
- So “(113) 555-1234” is not a real US or Canadian number.
Leeds: the +44 113 code
In the UK, Leeds (West Yorkshire) uses the area code 0113. Dialled from abroad, the leading 0 is dropped, so a Leeds number is written +44 113 xxx xxxx. That is the most common real phone number that “starts with 113”.

Frequently Asked Questions
What area code is 113?
In the UK, 0113 (written +44 113 from abroad) is the area code for Leeds, West Yorkshire. In the North American Numbering Plan (US, Canada and much of the Caribbean) there is no area code 113: area codes have the form NXX, where the first digit is 2 to 9, so no city or state uses 113.
Which area code should I use if a phone number starts with 113?
If it is just the three digits 113, it is a short service number in some countries (for example the State Police in Italy) and needs no area code. If it is a UK number like 0113 123 4567, 0113 already is the area code (Leeds); from abroad dial +44 113 123 4567. If it is any other longer number written with 113 first, you are probably missing the real area code or country code, or the 1 is the long-distance prefix followed by a code such as 13x that does not exist. Ask the person for the full number in international format (+country code, then number).
Is 113 a valid phone number in the United States?
No. In the US and Canada, 1 is the long-distance/trunk prefix and three-digit service numbers follow the N11 pattern (211, 311, 411, 511, 611, 711, 811, 911), none of which is 113. Dialling 113 on its own does not reach a public service.
What area codes look like 113?
Real area codes close to 113 include 213 (Los Angeles), 313 (Detroit), 413 (western Massachusetts), 513 (Cincinnati), 613 (Ottawa), 713 (Houston), 813 (Tampa) and 913 (Kansas City area of Kansas).
Is there a 113 area code outside North America?
Many countries use variable-length area codes beginning with 0 (for example 0113 is the Leeds code in the UK, written +44 113 internationally). That is why you may see +44 113 numbers: they belong to Leeds, not to an area code 113 in America.
