Ideal if you're on the go and still want a landline for a professional look. Works well and has enough options to scale up, or down.

Leenders Advice

Have been using Rinkel for a while. Recently had recordings made: cheap and quickly arranged. Do you want a landline number, but no landline? Then Rinkel is excellent. We will remain customer for a while.

Frequently asked questions about a 088 number

088 numbers are issued in a series of 100. For example, 088-100100 to 088-100199. This means only the last digits of your number series differs, which is ideal for multi-department companies or team members, since this allows you to keep a single recognizable number.

As soon as we have received all your information, we will contact the ACM directly and apply for your series. The application process can take up to three weeks. Would you rather be reachable right away? Then choose an 085 number.

No, unfortunately WhatsApp Business cannot be used in combination with 088 numbers. Do you want WhatsApp Business? Then use a 085 number.

It is possible that your desired number series it not available or has been requested by someone else. In cases of the latter, a lottery takes place. If the other party wins the lottery, the ACM will then propose a different number series to you.

You will receive an invoice from Rinkel in addition to a one-time invoice from the ACM. Unfortunately, we are unable to bundle all the fees together. The ACM invoice will be sent to the contact details you provided in your original application.

No, you can decide how many of the numbers you wish to use from the series.You only pay for the numbers that you use, which makes a 088 series via Rinkel ideal for growing organizations.

What is a 088 number?

A 088 number is a telephone number that is not confined to a city or region. 088 numbers are issued in series of 100, 1000 or 10 000 units. Thus you can assign different departments, branches, or employees a personal number within a uniform number series.

an example of a 100 number sequence: 088-100100 to 088-100199

Do you want to order a 088 series? Then please keep the following in mind:

  • Mandatory registration with the ACM - we handle everything for you!
  • Issued only per 100, 1,000 or 10,000 pieces
  • The series may only be used for one company
  • A 088 application can take up to 3 weeks

If your company is not planning any major expansion within the next 5 years then we recommend choosing a 085 number or a regional number instead. These numbers can be activated immediately and chosen online via Rinkel.
