A no objection certificate (NOC) does the same when an agency sends for a brand it doesn't own. Operators and regulators in Saudi Arabia, the UAE, Qatar, Kuwait, Bahrain, Oman, Egypt and Jordan usually ask for one, signed and stamped, with a copy of the commercial registration. ## How to write a sender ID authorization letter 1. **Pick the country and letter type:** Choose where the messages go, then an LOA (your own brand), a NOC (an agency sends for your brand) or the Saudi-style bilingual letter. 2. **Enter the company and signatory:** Use the legal name and registration number exactly as they appear on your commercial registration or trade licence. Add Arabic versions if you have them. 3. **List the sender IDs:** Add each sender ID with its message type and one sample message. Each ID is checked against the country's format rules as you type. 4. **Print, sign and stamp:** Save as PDF or download the Word file, print it on letterhead, sign it, stamp it with the company seal and send it with the supporting documents. ## What goes into a sender ID authorization letter Operators register an alphanumeric sender ID only when they can tie it to a legal entity that is entitled to use the name. The letter is how you make that link in writing: who you are, which names you want, what you'll send, and that you take responsibility for it. The generator builds every letter from the same set of fields, so nothing that operators routinely check is left out. - Company details: legal name, commercial registration or trade licence number, registered address and contact. - Date and, for Saudi letters, the Hijri date alongside the Gregorian one, plus an optional reference number. - Addressee: the SMS provider filing the registration, which then submits to the regulator and the mobile operators. - The sender IDs, each with its message type: transactional, promotional or OTP. - A sample message, so the operator can see the sender ID matches real traffic. - Declarations: you own the brand or trademark, you're responsible for content, you message only consenting recipients and offer an opt-out. - Validity, the authorized signatory's name and title, a signature line and space for the company stamp. ## LOA, NOC or Saudi-style bilingual: which one you need Use a letter of authorization when the company that owns the brand is also the one sending. It authorizes the provider to register the sender ID and use it for that company's messages only. Use a no objection certificate when someone else sends on the brand's behalf, such as a marketing agency, a reseller or a software platform. The brand owner confirms it has no objection to that party using its name, keeps responsibility for the content and can withdraw the permission in writing. The agency usually adds its own registration documents. The Saudi-style bilingual letter puts formal Arabic and English side by side, shows the Hijri date and has a field for the Unified National Number. It's the format most Saudi submissions end up in, and it reads well in the UAE and the rest of the Gulf too. ## Country notes for the Gulf and the Middle East Registration is mandatory in all of these markets, and the letter goes through your SMS provider to the regulator and each operator. We confirm the exact list for each country during onboarding. - Saudi Arabia: the Communications, Space and Technology Commission (CST) sets the rules; stc, Mobily and Zain register the IDs. Promotional IDs may need the “-AD” suffix. - United Arab Emirates: TDRA rules, registered with etisalat and du. Promotional sender IDs start with “AD-”. - Qatar, Kuwait, Bahrain and Oman: the national regulator plus each operator; a commercial registration copy is the usual companion document. - Egypt: NTRA rules, with Vodafone, Orange, etisalat and WE. A commercial register extract and tax card are often requested. - Jordan: TRC rules, with Zain, Orange and Umniah. ## Why sender ID letters get sent back Most rejections come down to a mismatch between the letter and the supporting documents, not the wording of the letter. - The company name differs from the commercial registration, even by one word or abbreviation. - The registration or trade licence has expired. - No signature, no stamp, or a signatory who isn't on the registration and has no power of attorney. - The sender ID doesn't resemble the company or brand name and there's no trademark certificate. - Generic sender IDs such as “INFO”, “SMS” or “OTP”, which operators usually refuse. - Promotional IDs without the country's required marker, such as “AD-” in the UAE. ## Sender ID letter questions ### What is a sender ID authorization letter? It's a letter on company letterhead, signed by an authorized signatory and stamped, that authorizes an SMS provider to register one or more alphanumeric sender IDs for your company and use them for your messages. Operators ask for it so every sender name is tied to a legal entity that is entitled to use it. ### What's the difference between an LOA and a NOC for a sender ID? An LOA comes from the company that owns the brand and also sends the messages. A NOC comes from the brand owner when another party, such as an agency or reseller, sends under the brand's name. The NOC confirms there's no objection, limits use to the brand's own messages and can be withdrawn in writing. ### What does a sender ID NOC letter need to include? The brand owner's legal name, registration number and address; the agency's name; the provider; the sender IDs and message types; a sample message; declarations on brand ownership, content responsibility and consent; a validity period; and the signatory's name, title, signature and company stamp. The generator adds all of these. ### Does the letter have to be in Arabic for Saudi Arabia or the UAE? English is commonly accepted, but a bilingual Arabic and English letter avoids questions, especially in Saudi Arabia. Choose “Bilingual” to get both versions side by side on one page, with the Arabic written in formal letter style and laid out right to left. ### Which documents do I need besides the letter? Usually a valid commercial registration or trade licence, a copy of the signatory's ID or passport, a trademark certificate if the sender ID differs from your company name, and for agencies the brand owner's NOC plus the agency's own registration. The checklist under the tool adapts to the country you pick. ### Is this template approved by CST, TDRA or another regulator? No. It's not an official regulator form. It follows the standard format operators usually request, and we confirm country-specific requirements during onboarding, including any extra wording or documents a particular operator asks for. ### Can an agency register a sender ID for a client's brand? Yes, as long as the brand owner signs a NOC that names the agency, and the sender ID matches the brand's trade name or a trademark it owns. Operators usually also want the brand owner's registration document, so collect it from the client before you file. ### Is the information I type stored or sent anywhere? No. The letter is built entirely in your browser. Nothing you type is sent to our servers or saved, and the PDF and Word files are created on your device. Close the page and the data is gone.
