Identify Landline vs Cell Phone, Carrier and Active vs Disconnected

Verify Phone Number TypeStep 1.   Select the Service Level

Standard Line Type and Carrier
90-95% accuracy for line type [details]
The most affordable and popular service to identify line type. The data is updated monthly. However, this service does not check for line number portability (LNP) and will miss the mark if someone moved their landline number to a mobile carrier. Our Standard Service also reports the original carrier at the time the line was issued as well as location. Download a Sample Report Here

Advanced Line Type and Carrier
Real-time LNP lookup, 99.9% accurate [details]
The best choice, if you need real-time accuracy for line type and the current carrier. Our Advanced Service goes several steps further to check if the number was moved (ported) to a new phone company (Local Number Portability check - aka LNP). If a number was moved, this service reports the exact move (port) date. Numbers identified as Mobile will also include the SMS/MMS email address (giving you the ability to email text or media messages).

This is the most accurate line type service available and is a better choice if you need more accuracy regarding carrier name since many mobile numbers change Mobile carriers each month but less than 6% of landlines ever become mobile numbers. Download a Sample Report Here

Active Phone Number
Check if line is Active + Advanced service [details]
This service includes everything from the Advanced Line Type (LNP) service above plus it checks to see if the numbers in your list are Active or Disconnected phone numbers. Utilizing a real-time check of billing phone information records plus proprietary advanced search methods, this service often includes a billing name for many of the active landline numbers in your list as well.

  • Line Status. Using Real-time verification in carrier billing systems and other advanced proprietary methods the following statuses are reported
    • ACTIVE - Phone number with active billing status
    • INACTIVE - Disconnected phone number
    • INVALID - Phone number does not exist (e.g. invalid area code or not issued)
    • UNKNOWN - Status cannot determined

  • Billing Name. For active landline numbers, billing name may be provided
  • Line Type. Identifies how phone is connected to the network. For the Standard service it's the line type of the orginal carrier. The accuracy is still close to 95%, as vast majority of phone numbers have been transferred from one mobile carrier to another, keeping the line type unchanged. Carrier reported by Advanced and Active Phone Number services is 99.9% accurate.
    • LANDLINE - Wired home or business phone number
    • CELLULAR - Wireless mobile phone number
    • VOIP - Landline number leased to a Voice over IP provider
    • UNKNOWN - Invalid or not yet issued phone number

  • OCN. Operating Company Number (Carrier ID)
  • Carrier. Phone company (local exchange carrier) name. For the Standard service it's the original carrier (about 60% accurate due to number portability). Advanced and Active Phone Number services are 90% accurate, since porting is checked. Name discrepancy can occur when one carrier was acquired by another. For VOIP, will not see Vonage, Ooma, Google Voice or Skype, but rather a LANLINE carrier (e.g.,, Level 3 Communications) that has leased a range of its phone numbers to a VoIP carrier.
  • Date Ported. Date and time when phone number was last ported. We can report porting that occurred TODAY!
  • SMS Email*. For active cell phone numbers, SMS email (e.g. is provided
  • Location. Rate Center and/or Central Office location. It can be city name (SEATTLE), city abbreviation (NEWPORTBCH) or code (NWYRCYZN01)
  • State. 2-letter code for US State or Canadian Province
  • Time Zone. Time Zone of the phone number location (e.g. Eastern Daylight Time).
  • *Sending SMS or MMS email to Mobile Numbers. This is the simplest way to send text messages from the Internet or from your computer to mobile phones. These email addresses essentially act as a direct link to a carriers SMS gateway. Keep in mind that the length of an SMS email should be kept to fewer than 160 characters. If you are sending MMS there is typically no character limit, however, large files may be rejected by the carrier. While SearchBug provides this information with our Advanced Line Type Service and Active Phone Number Check, you, the end user, should have customer consent to avoid any FCC regulation infractions such as TCPA.

    SMS (Short Message Service) and MMS (Multimedia Messaging Service) are both used in mobile phones for non-voice communications. SMS is typically used to send text, while MMS is typically used to send images, music, animations, or other interactive documents, or files.
