Is your request due to telemarketing and other robo call phone scams? If they allowed 10,000 blocked numbers, I can tell you it still won't solve the problem. The Verizon blocked numbers were useless and it's time consuming to keep updating it with new numbers. TMs and scammers use fake numbers (which in my opinion, the phone company should disallow) and they change those numbers all the time. If this is your problem, I suggest looking into Nomorobo. com. I did and my TM calls went from 6 to 10 a day to zero. They have blocked millions of calls in the U.S. with no effort from the consumer and with no desired calls lost. Your phone rings once on TMs but then Nomorobo intercepts and blocks their call. If any do get through and you have the number, you can report it online instantly and they add it to their database. Most major landline carriers are now working with Nomorobo and it's free.
