This is the free NALENND™ wireless telephone number data scrubber. You can use it to identify invalid, landline, and wireless or cellular numbers in your telephone number list as a step toward TCPA and Wireless-do-not-call compliancy.
Enter up to 100 United States or Canadian 10-digit telephone numbers (one number per line) and receive a simple CSV data file identifying your wireless and landline numbers. This utility does not check ported telephone numbers but should still give you approximately 96% accuracy. We invite you to compare our findings with other vendors using the same number list.
