Are there any restrictions on the numbers to be used as caller IDs?

Moitele recommends to use legal, genuine phone numbers as caller IDs.  We also recommend our customers to be able to prove the ownership of the phone numbers when issues arise. Across the world, all the major telecom providers have improved their spam controls by deploying various tools and methods. Hence we recommend to make sure that the caller IDs match the following criterion - 

  1. Caller IDs should not be short numbers between 1-7 digits
  2. Every international calls should originate with a caller ID that also has the country code
  3. Customer has to make sure that the caller ID is not marked as SPAM.
  4. Do not spoof the caller IDs by randomly using some unknown number or other company's phone number
  5. Always buy and use only the numbers where you can prove the ownership
