The country code 0037 is no longer in use. It was originally assigned to the former country of East Germany (German Democratic Republic) before German reunification in 1990.
After reunification, East Germany was integrated into the numbering plan of unified Germany, which uses the country code +49.
If you encounter 0037 today, it might be an incomplete or outdated code. For modern purposes, check for additional digits to identify the exact country.
