The .cab zone is a generic extension linked to the word cab, which is the everyday name for a taxi in many English-speaking countries. A name in .cab tells passengers and clients that the site is about rides, whether it belongs to a taxi firm, a booking service, an airport transfer company or a driver with a small fleet.

A short history
The word cab is a short form of cabriolet, the name for a light horse-drawn carriage. It came to mean a hired vehicle for passengers, and over time it became the everyday word for a taxi in several countries. The .cab extension is a generic ending, so it is tied to the transport trade rather than to any one country, which suits firms that want a short and clear address for their service.
Who runs it
The registry operator sets the policy for the zone, and accredited registrars sell names to customers. Rules can change, so the terms in force at the time of purchase apply. For a transport business, read the operator's policy alongside the rules that govern your type of service.
Rules in practice
- Open registration: generic zones are usually open to businesses and individuals, subject to the operator's acceptable use terms.
- Business details: the registrant should be the licensed operator of the service, under the same name shown in its licence papers.
- Characters: letters, digits and hyphens are allowed, and a label can reach 63 characters.
- Continuity: a booking system that depends on the domain should be renewed well ahead of expiry, so that no ride request is lost.
Who uses .cab
- Taxi companies and radio cab operators that take bookings online.
- Airport transfer services and private hire firms that offer pre-booked journeys.
- Drivers and small fleets that present their vehicles and service areas.
- Transport apps and trip planning tools that explain how to order a journey.
Strengths
- The word states the subject at once, which helps passengers find a ride quickly.
- It is short and easy to say on the phone or to remember from an advert.
- It fits neatly on a vehicle door, a roof sign or a booking card.
Things to keep in mind
- Taxi and private hire services are licensed in many places, and rules on vehicles, drivers and insurance differ, so check the local requirements before you advertise.
- Passengers should be able to see the licence and operator details, so publish them clearly.
- Visitors may still type .com or a national address first, so consider whether you need more than one.
- A booking site must be reliable at busy hours, so test it before the busiest weekend of the season.
Tips before you register
- Check the name in .com and on the map and review platforms where your service is listed.
- Use the operating company's name exactly as it appears in its registration documents.
- Publish your service area, contact numbers and booking steps in the language of your passengers.
- Set up mail authentication records before you send booking confirmations or receipts from the domain.
- Turn on auto-renewal and use two-factor login, so that a changed password cannot send bookings elsewhere.
Frequently asked questions
Can any driver register a .cab name? Generic zones are usually open, but the operator's policy applies. Whether you may run a transport service under the name depends on local licensing, which you should check separately.
Is .cab only for taxis? No. Airport transfers, chauffeur services, delivery companies and trip planning tools can use it too, as long as the site matches the name.
Does .cab help a booking page appear in search? It helps people see the subject, but clear service areas, accurate contact details and genuine reviews matter more.
