The trade licence question: what a legitimate mobile van operates under
Every mobile mechanic should trace back to a trade licence from an emirate's economic department, such as Dubai's Department of Economy and Tourism or the Sharjah Economic Development Department, with an activity that actually covers vehicle maintenance. A licence for general trading or car washing does not authorise mechanical work, and some emirates require a specific mobile or onsite variant of the repair activity before a van can legally work away from fixed premises.
Free-zone licences add a wrinkle: a free-zone company is generally restricted to operating within its zone, so an outfit sending vans across the emirate on one may be outside its permitted scope. Ask for the licence number before booking and check the company name matches your invoice. Legitimate operators hand this over without friction. Platforms help too; tamam lists verified vendors whose businesses are attached to real bookings, payments and rebooking history, a very different accountability picture from a number on a lamppost sticker.
