What is the area code for Middlesex?

Answer 1

Most of Middlesex uses the London area code of 020, with eight digit local numbers.

Some small parts use other codes. For example, Uxbridge area uses the code 01895 with six digit local numbers.

Answer 2

You need to be more specific. A lot of Middlesex is covered by the London area code, 020, but there are other codes covering the outer edges of this area too.

Many numbers in that area will be of the form (020) xxxx xxxx.

If you see '0207' or '0208' then the person writing it, has written it incorrectly.

the address of the hotel is on Bath Rd., Hayes? Middlesex. It is 1km from Heathrow

Answer 3

There are several UK area codes that cover portions of Middlesex.

020 = greater London

01784 = Staines

01895 = Uxbridge

01923 = Watford (including Northwood)

01932 = Weybridge (including Sunbury-on-Thames)

In international format, replace the trunk prefix 0 with country code +44.

(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, Japan uses 010, Australia uses 0011, and many other countries use different prefixes.)
