You could have a separate table that stores the next companyNumber to use. then append that to the end of the string. If you did this in SQL when you insert the record it would prevent multiple clients getting the same number.

Each time the InsertCompany statement runs, you read the current number, append it to the code value you want to use and increment the number by one.

Insert into CompanyTable
Set
CompanyName = @CompanyName
Code = CONCAT((SUBSTRING (CompanyName, 0, 5) ), Select NextCompanyNumber from CompanyNumberTable)

Update CompanyNumberTable Set NextCompanyNumber = NextCompanyNumber+1

Something like the above might do the job.
