0121 Numbers – Buy Your Number Now

Before selecting your new 0121 telephone number let us explain a little more about what this Birmingham-based geographic number can do for your business. Firstly, making the decision to utilise a 0121 contact number is an instant way to inform your callers that you are a local company and that you are situated nearby in a familiar location.

In addition, as a regular landline telephone number 0121 gets typically charged at standard rate – that means callers are also familiar with associated call fees when contacting you.

Phoning your business from abroad via a 0121 is pretty straightforward. All callers will need to do is to add +44 to the number and lose the 0. That makes your 0121 number look like this, +44 121 xxx xxxx.

What do I need to know before I buy an 0121 number?

UK telephone numbers beginning with 01 or 02 relate to particular areas of the country.

The short answer to where numbers that start with 0121 relate is Birmingham in the West Midlands.

However Birmingham is a big city, the country’s second largest in fact, so the 0121 prefix code also covers many of Birmingham’s districts, suburbs and satellite towns, such as West Bromwich, Edgbaston, Halesowen and Sutton Coldfield.

During a comprehensive overhaul of the UK telephone network by The Post Office in the 1960s, Birmingham was allocated the area code 021 in recognition of its status as the country’s second largest city. This code preceded a further seven digits to make up telephone numbers in the area.

This group of seven numbers began with a 2 or 6 for telephones in Central Birmingham while numbers to the city’s North side were 021 3XX XXX, East started with a 7, West with 5, while South was 4.

Choosing your 0121 number

Within these larger zones, districts initially had their own codes, such as 021 472 XXXX for Selly Oak.

This meant that people were able to find a clear indication where around the West Midland area a home or business would be located just by looking at its telephone number. Other areas which had different area codes included Acocks Gree, Ashfield, Aston Cross, Beacon, Bearwood, Birchfield, Blackheath, Calthorpe, Castle Bromwich, Druids Heath, Edgbaston, Elmdon, Erdington, Fordbridge, Four Oaks, Great Barr, Halesowen, Harborne, Highbury, Hillside, Kings Norton, Oldbury, Rectory, Rowley Regis, Rubery, Sheldon, Shirley, Smallbrook, Smethwick, Solihull, Springfield, Stechford, Stone Cross, Streetly, Sutton Coldfield, Tipton, Wednesbury, West Bromwich and Woodgate.

In more recent times, however, the explosion in the number of telephones, faxes, modems, and other internet and communications technology equipment blurred the strict geographical demarcation of the original numbering system.

Why buy an 0121 number?

This dramatic increase in the demand for numbers led in 1995 to all 021 numbers being modified with the addition of an extra digit to signify these related to a geographical area. This meant that every 021 number became 0121 overnight, forcing businesses and public agencies to change their signage and letterheads and also for IT equipment to be reprogrammed to take account of the new format.

Further blurring of the locality information contained in telephone numbers followed the deregulation of the telephone market when British Telecom was removed from state ownership and sold off to the private sector. This opened the market to competition so today multiple companies are able to offer landline numbers in an area where once British Telecom or the Post Office was the only provider. For example, in recent years Virgin Media has offered numbers starting 0121 250 xxxx to customers throughout Birmingham and that part of the West Midlands.
