st: Dropping Alphanumeric elements from variables

I have a dataset which includes household ID variables in an alphanumeric format. The letters are abbreviations of the village a household comes from. In addition to being in an alphanumeric format, the HH ID has a year element so that the HH ID for 2010 is slightly different than it was for 2009. I am looking to convert the alphanumeric HH id into a unique id for constructing a panel. I need to replace the 3 letter village abbreviations with a 3 digit number plus I need to drop the year id.
An example may clarify. Right now HH IDs look like BTG09A00001, BTG10A00001, BGM09A00027, BGM10A00027.
I want to replace the village code (BTG, BGM) with a numerical sequence. I also want to drop the year sequence (09, 10) so that HH ID is consistent for the HH across years, and I want to drop the A, which plays to role in my dataset. Ideally, this would compress the 4 HH ID I gave as examples into just 2 IDs that would look like 10100001 and 10200027.
Any help would be greatly appreciated.
