Registering your number with the National Do Not Call Registry (NDNCR) is a great way to reduce the number of telemarketing calls you receive. However, you need to understand that joining the Do Not Call List does not put an end to all telemarketing phone calls. Many phone consumers who register their numbers make the mistake of believing that once they become members of the NDNCR, that telemarketers will stop phoning, and that if they receive calls they can file a complaint. This is not entirely true.The National Do Not Call Registry has rules that you need to understand if you want to effectively protect your rights as a phone consumer. Thus, if you were to read the guidelines of the NDNCR, you would find that in certain cases it is still legal for telemarketers to phone you despite the fact that you have registered your numbers.When are telemarketing calls legal? There are essentially two types of solicitation calls that are permitted:1 – An established business relationship (EBR) exists – If you have an EBR with any company, which occurs as soon as you have made a purchase, the business is legally allowed to contact you with solicitation phone calls. Therefore, you will not be able to file a complaint with the NDNCR, unless the company continues their telemarketing calls after you have asked them to stop by requesting to be placed on their internal do-not-call-list.2 – Calls made by non profit organizations, survey groups, government organizations – Charity, survey, and political calls are exempt from the Registry. Calls of a non-profit nature are legal, and complaints cannot be filed against them. Therefore, regardless of how annoying you may find these calls, your best hope to making them stop is to tell the person that you would like to be taken off their call list. That said, keep in mind that by law these organizations do not have to keep a do-not-call-list.Last but not least, you need to know that if you have not yet been registered with the NDNCR for a full month (31 days), you should not expect a dramatic decrease in telemarketing calls. The reason is the Registry allows telemarketing firms a month to update their call lists. Therefore, to reduce calls from telemarketers, it is in your best interest to inform all of those who contact you that you would like to be placed on their do-not-call-list. That way if they phone you again, you will be free to file a complaint.Visit the National Do Not Call Registry’s websites and find out more about telemarketing calls, so you can learn what is legal and what is not.
