The PSMA stands for the 'Public Sector Mapping Agreement'. It licences all public bodies to legally use Ordnance Survey maps and address databases for their work.

This includes bodies such as District, Borough and County Councils, the Police, the NHS, and, of course Town and Parish Councils. It was established by Central Government and is funded centrally, removing the need for each public body to pay for the mapping seperately. This means it is 'free at the point of use'.

As a result you will need a PSMA Licence Number if your Town, Community or Parish Council wishes to use XMAP as it contains the Ordnance Survey Maps and Address Databases provided through the PSMA.

Registering for the PSMA

Registering is easy, simply fill in the form using this link and select the 'I am applying to join the Public Sector Mapping Agreement (PSMA) and agree to the terms & conditions for both the PSMA and Royal Mail's PSL Use Terms' option in the Application Type Section.

After registering you will be assigned a PSMA license number which will look similar to this: 100012345.

Signing Up with XMAP

Once you have your licence number you can then sign up to XMAP and enter the number when prompted in the sign up form.

You will not be able to sign up to XMAP without a valid PSMA number.

If your number is something like 9999999999 or 1234567890 or 000000000000 then you know you've got a problem and should get in touch.

You can do this by raising a support ticket within XMAP's Admin Panel.
