Here’s what you need to know about Be very careful with calling these numbers: your bill can skyrocket -!, Here are the details …Nowadays, there are many users who have contracted a rate in which the calls are unlimited , so we are used to the fact that the calls we make do not involve an additional cost in our invoice to end of the month.

The reality is that few users know what it means for a phone number to begin with 806 and the costs that can be incurred in making a call to numbers with a prefix 800 or 900, since we are not always clear what they are or how much to cost a call . There are numbers that are outside the flat rate of calls that we can have contracted. Calls to these numbers are premium rate calls and must be paid separately. Next, we will explain to you which numbers you have to be careful with so that your bill does not skyrocket.

What are special rate calls

They are those calls that do not enter the rate that we have contracted and for which, in some cases, we must pay separately. However, in some special rate numbers the call is free. That is why we are going to tell you what the special rate numbers are and how much it can cost to call any of them.

Numbers 800

Calling a number that begins with the prefix 800 is free , since the cost of the call is paid by the person who receives it and not by the person who makes it. But this is not the case for all numbers that begin with eight followed by two zeros. There are some numbers that involve a high cost.


This prefix is ​​used in adult services . The numbers 803 are generally erotic content. The cost of the call will be very high and we recommend looking at the fourth digit of the number, since if it is higher than 6 the price will be even higher and it is normal that you have to authorize this type of calls in advance with your operator.


Telephone numbers beginning with entertainment such as tarot, raffles or television contests. As in the case of 803, the amount of the call varies depending on the number that follows the 806, even costing more of 3, 50 dolars per minute .


The numbers 807 are related to professional services (counseling, doctors …). If we make a call to this type of number, it will have a high cost so we recommend that you think twice before making it.

The fourth figure determines the cost

If we are about to call any of the numbers with the aforementioned prefixes, it is advisable to look at the fourth digit of the number, since it is the one that determines the cost of the call. The higher it is, the more you will pay .

From 0 to 1: calls from the mobile cannot have a price higher than 0, 56 dolars per minute. Greater than 6: As we mentioned previously, it is necessary to have authorized your telephone company to allow you to call these numbers. Each minute has a cost of 1.3 dolars onwards and there is no maximum limit. It is highly recommended to deactivate this type of calls to avoid surprises in our bill. If for any reason we need to make use of them at any time, we can always request their activation again.

Numbers 900

If you’ve ever wondered how much it costs to call a number that starts with 900, you’ll like the answer. Calling a number that begins with 900 is free , since the call is paid by the person who receives it. For example, some companies use the numbers 900 for free customer service. On some occasions we may call a number 900 and it does not work. This happens because some companies block calls to this type of number from certain places.


They have usually been used by the Public Administration : Social Security, Tax Agency etc … When we make a call to a 901 we pay part of the call (the amount that was originally equivalent to the cost of a local call) and the owner of the number pays the rest.

In this case, the rates for calls to a 901 are not free and neither cheap . In recent years, rates to numbers 901 have been frozen or even increased in price, while the rest of calls have become cheaper. Especially calls to numbers 901 from the mobile are very high. Depending on the operator from which we call, a call to a 901 can cost from 0, 22 dolars to more than 2 dolars if the call is made from the mobile.

This numbering can no longer be used for customer service and whenever it is advertised it must be accompanied by a traditional geographic numbering, which is the one to be used.


In the case of numbers 902, users have to pay the full cost of the call. A call lasting 5 minutes can cost around 3 dolars from a mobile phone and 1 dolars from a landline.

A few years ago, gas and electricity companies were prohibited from using 902 as a customer service number . Prohibition that has been extended to all companies that offer a basic service to the consumer: insurance, energy, water and sanitary transport, among others. From the year 2020 these numbers cannot be used for any customer service client and in the event that a company uses a 902 for another type of services, must be accompanied by a normal number with geographical prefix.


Numbers starting with . for each call that is indicated in the advertisement that announces the phone number.


Like numbers beginning with 907 and 909, the 908 are numbers that users connect over the Internet to provide a service and must be expressly requested, making it more difficult to find surprises on the bill.

As it happens in numbers 803, 806, 807 and 905, the fourth digit after 907, 908 or 909 is determinative.

From 0 to 4 we will access online services. From 5 to 9 it is a service for adults.

Numbers 118

These numbers are used as a phone book. Prices at these numbers vary widely depending on who is providing the information. The CNMC published a report detailing that the average price of a one-minute call was 5, 56 dolars.

In addition, these types of numbers offer “call progression” , that is, instead of giving us the number they offer to make the call for us. With the intention of making our lives easier, a third party calls 118 so that a short call can easily last for several minutes.

Fortunately, several measures have been adopted to avoid these problems:

Previous voiceover informing of the price. Limitation of 10 minutes per call. Rate without call establishment. If the “call progression” exceeds 2.5 dolars per minute, a “formal and express” request from the user will be necessary. Calls to numbers 118 are not considered special rate services . From the OCU they request that they be considered this way for all purposes, but they have not yet achieved it. From what you already know with all the numbers with which you have to pay special attention if you do not want to get surprises in your bill.
