Welcome.

Next time you ask for an alternative it would be grateful if you could provide more information like an address, website address, geographical fax number, etc.

However, I found the following:-

www.easylocums.com
Reg. Office: Imperial House, 17A Greenhead Road, Huddersfield, West Yorkshire, HD1 4EY


A 192.com search reveals EasyLocums has two addresses neither of which had any contact number.

An internet archive reveals they've been using 0870 since 2003 ish.

You could email them and ask them for a fax number (if you can think of a reason for wanting their fax number) and see if that is a geographical (which may help us) or another 0870.

The telephone area code for West Yorkshire is: 01484.

I'm out of ideas.  Can anyone else help?
