Netherlands Phone Number Validator & Carrier Lookup
The Netherlands launched one of Europe's first number-portability schemes back in 1999, so a Dutch number's range is an especially poor guide to who serves it now. Veriphone returns the originally allocated network — KPN, Odido (the former T-Mobile) or Vodafone — plus line type, and with mode=current the operator actually serving a ported line. Mobiles sit in 06; the rest is geographic or a service range.

Netherlands phone number format
Netherlands numbers carry the +31 country code with a national trunk prefix of 0, dropped in E.164 format. Mobile and fixed-line ranges are distinguished by their leading digits and returned as a line_type you can filter on.
Netherlands mobile operators & prefixes
Each mobile prefix is allocated to a specific operator. Veriphone returns that operator from the ACM (Autoriteit Consument & Markt) numbering plan, along with line type.
Plus 11 smaller networks (MVNOs), including Lycamobile, ASPIDER Solutions Nederland B.V., Tele2, Glotell B.V (V-Tell NL), Lancelot. Veriphone resolves each to its host network.
Fixed-line area codes
For landline numbers, Veriphone returns the city or region where the numbering plan resolves one. Mobile numbers are non-geographic and carry no city.
Questions about Netherlands number validation
Why does the leading 0 disappear in the +31 format?
The 0 is a domestic trunk prefix and is dropped in international E.164 form. An Amsterdam line dialled as 020 123 4567 becomes +31 20 123 4567, and a mobile dialled as 06 12345678 becomes +31 6 12345678.
Can I tell a mobile from a fixed line by the number?
Yes. Mobiles always start with 06 followed by 8 digits, while geographic fixed lines begin with a 2- or 3-digit area code (020, 010, 070 and so on). Non-geographic ranges such as 088, 085 and 0900 belong to neither category.
Does the area code reveal the carrier?
No. Area codes map to a geographic region rather than an operator, and because numbers can be ported the range holder may no longer be the operator serving the line. Use mode=current to identify the operator actually serving a ported number.
What are 088, 085 and 0900 numbers?
088 numbers are non-geographic company ranges often used by larger businesses, 085 is used for internet-based services, and 0900 numbers are paid service and information lines. None of these are tied to a city area code or to a single mobile network.
