Wants $4.95 a month in some states to keep your number out of their phone directories.

In a case of shooting itself in the proverbial foot, Verizon’s argument its $4.95 monthly fee to keep your landline number out of their directory is justified has revealed a way to avoid paying it at all, saving $60 a year in unnecessary fees.

The company acknowledged that customers who drop their landline in favor of a cell phone will have an unlisted number at no additional charge.

A Network World columnist asked Verizon why it costs so much to do so little.

“Why do you charge me $4.95 per month just so that I can keep my phone number unpublished? Please do not merely tell me that you are allowed to charge me this fee because I already know that. What I want to know is WHY do you do it? What cost are you passing along? … I would appreciate as much specificity in your reply as possible.”

Here’s the reply from a media relations spokesman, who first consulted with “a key member of product management with oversight for (unpublished) numbers”:

“The cost charged to offer unlisted phone numbers is chiefly systems and IT based. Specifically, the costs we incur and factor into the monthly charge involve three things: quality control, data integrity and the interface we have with other carriers and directory publishers. These activities help us protect the feed of customer information we have, and must protect, when customers request that their telephone number remains private when requested.”

Stop the Cap! decided to pose our own follow-up to Verizon’s customer service department:

“If we were to drop our landline and choose a cell phone instead, would our number be listed or unlisted?” we asked.

Verizon’s reply:

“Cell phone numbers are not listed in our directories and are not available from directory assistance unless you pay an additional fee for our listings service. The rates vary by state.”

Customers switching landline providers with the intent of keeping their currently listed phone number may, however, remain in the telephone directory if Verizon forgets to remove the listing after the customer disconnects service. But there should be no charge to remind Verizon you disconnected service and want the listing deleted.

As a consequence of deregulation, many states no longer keep tabs on ancillary fees charged by Verizon for these services, which are largely based on what the market will bear.
