As a registered forum member, please can you report any feedback on the database through the Requests section of the forum. That way we keep requests for alternatives, suggestions of alternatives and feedback (positive and negative) all together in one section of the forum.

By feedback, I mean:

• numbers that no longer work;
• unverified numbers (on the table with the blue background) that do work and can therefore be verified;
• numbers that aren't listed that you know to work;
• any other 08 numbers that the company in question may operate and that aren't listed on SAYNOTO0870.COM.

I think that the question of what 0845 583 0086 can now be answered. I believe it is a branch of HSBC, although I have no idea which one. There is an unverified entry in the database which says "Any HSBC Number starting 0845 583 can be called using 01226 83". There is also one unverified entry for a branch which is a 0845 583 number.

Another online business telephone directory to try is: http://www.ukphonebook.com/directory_enquiries.

You can search using a partial business name:
e.g. starbucks* returns starbucks coffee co nottingham

They also have a dialling code lookup
