Allies was founded by two people in 1987. Today we have a team of twenty and over 9,000 businesses using our solutions.

We are best known for providing some of the UK’s largest – and smallest – businesses with the postcode lookup technology that you use when filling in your address online.

2018 was our 31st year in business

Passing our 30th anniversary didn't slow us down. We're continuing to build on our successes and break new ground.

We began conducting and releasing our own industry research, and are always striving to make our solutions better for our users.
