the released country code +37 was later reused as the initial digits of several new codes for european countries that became independent states at the time (e.g.: +370 for lithuania, +374 for armenia, +375 for belarus, etc.), as well as some microstates whose telephone networks had formerly been integrated to those of surrounding larger countries (e.g. +376 for andorra, +377 for monaco and +378 for san marino).
