Where AliExpress Asks for a Phone Number
Signup is the first point. AliExpress still allows registration with an email, but on most regions the flow now inserts a phone step before the account is usable, and accounts created through the app are asked earlier than accounts created on the website. The second point is login risk: a sign-in from a new IP country, a new device, or after a long gap triggers a "verify it is you" check that sends an SMS to the number on file, or asks you to add one if there is none.
The third point is promotions. New-user coupons, the "choice" bundle discounts, and the coin-based deals are tied to a verified phone because that is how AliExpress limits one welcome offer per person. An account without a number sees the coupon but cannot apply it at checkout. Sellers who run promotions on AliExpress see the same enforcement from the other side.
Checkout itself does not require a phone number for card or PayPal payments in most countries, though the shipping address needs a contact number for the courier, and that can be any number the courier can reach, not the verification number.
Where Alibaba.com Asks for One
Alibaba.com is the wholesale side. Buyer registration asks for a phone number as a required field and verifies it by SMS before the account can message suppliers. Posting an RFQ, the form where you describe a product and let suppliers bid, is gated behind the same verification plus a company name, which does not have to be a registered entity for a buyer account. Trade Assurance orders, the escrow-style payment path, work once the buyer account is verified.
The supplier side is a different world. A Gold Supplier or verified-supplier account requires business licence uploads, a company bank account, and in mainland China an on-site or video inspection by a third party such as SGS or TÜV. Phone verification is one line on a long form there, and a temp number does not get you past the rest. If you are buying, the SMS step is all you need; if you are selling on Alibaba.com, plan for documents.
AliExpress and Alibaba.com accounts are separate registrations, though you can log in to one with credentials from the other in some regions. A number used on one may be recognised on the other, which is relevant to the recycling problem below.
Which Countries Pass on Each Platform
AliExpress is one of the least picky major platforms about number origin. Its customer base spans almost every country, so the SMS gateway accepts numbers from the United States (+1), the United Kingdom (+44), Germany (+49), France (+33), Spain (+34), Poland (+48), Brazil (+55), Russia (+7), and most of Southeast Asia without complaint. The number country does not need to match the shipping country or the site region you browse in. Delivery is fast on European and North American routes and slower but reliable on Russian and Brazilian ones.
Alibaba.com is more selective on buyer accounts and considerably more so on anything supplier-side. Buyer registration with a US, UK, German, or Dutch (+31) number verifies without issue. Some ranges in Southeast Asia and Africa return "phone number format incorrect" even when the number is valid, which is a whitelist problem on Alibaba's side rather than a delivery problem, and the fix is a different country rather than a retry.
Pick a mobile-range private number on TempNumber.me for either platform. Both run a basic carrier check and both have blocked large public inbox numbers after seeing them on thousands of accounts. If you also want a number for Temu, which shares many of the same behaviours, the details are at /blog/temp-number-for-temu.
Step by Step for a New AliExpress Account
AliExpress sends a six-digit code with a window of about five minutes, and it limits resends to a handful per hour before the number is paused for the day. Open the TempNumber.me dashboard first.
- Take a private activation on TempNumber.me with AliExpress as the service and one of the countries above. Leave the activation open in the dashboard.
- Register on AliExpress with an email you control. When the phone prompt appears, either at signup or at first login, select the matching country and enter the number without the country code.
- Request the SMS, copy the code from the dashboard as it lands, and submit. The account is now marked verified in Account Settings.
- Set a password on the account rather than relying on the email one-time links, and turn on the email login alert. If AliExpress offers to make the phone the primary login, decline; keep email as primary so a later re-verification does not lock you out.
- If a coupon was the reason for verifying, apply it in the same session. Some welcome offers expire 24 hours after verification.
The Recycled Number Problem on Alibaba Group Accounts
Alibaba Group properties keep phone-to-account mappings for a long time, and they surface the previous mapping in a way most platforms do not. Enter a number that was previously registered to an AliExpress account and, instead of a fresh signup, you may be shown a login prompt for that older account, or a message that the number is already in use. On Alibaba.com the same situation can attach your new registration to a stale company profile, which then fails RFQ posting because the profile is incomplete or flagged.
This is why a shared public inbox number is a poor choice for AliExpress and Alibaba specifically. Those numbers have been registered on both platforms many times, and the account you get, if you get one, inherits whatever the previous users did. A private activation from TempNumber.me is issued to one customer at a time, and the number pool is rotated so that a number recently used on AliExpress is not offered for AliExpress again in the same window. How rotation works across the pool is at /blog/number-recycling-explained.
If you do hit the "already in use" message on a fresh activation, do not retry it. Cancel the activation, take a different country, and register again. Requests for credit on activations where the number was refused are handled case by case via support@tempnumber.me.
Login Checks After the Account Exists
The verification number stays attached to the account, and AliExpress will send a code to it on risky logins. If the activation has expired by then, you cannot receive that code. Two things prevent a lockout. The first is a verified email on the account, since AliExpress offers email as an alternative on most login challenges. The second is not changing devices and IP countries more than you need to; a VPN that hops countries is the most common trigger.
For accounts you will use for months, especially a buying account with Trade Assurance orders in progress, a rental number is the better fit. TempNumber.me rentals hold a number for a fixed term so the login codes keep arriving. Which duration suits which use is explained at /blog/how-long-do-temp-numbers-last.
Who This Is For, and Who It Is Not For
The typical reasons to keep a personal number off AliExpress are ordinary. Marketing SMS from AliExpress and its sellers is persistent, the number is visible to any seller who ships to you, and a data leak on a marketplace of that size exposes it widely. Dropshippers and small resellers who operate several buyer accounts to separate suppliers or clients have a second reason: one number per account keeps them independent. Wider guidance for sellers is at /blog/temp-number-for-online-selling.
It is not for building a supplier presence on Alibaba.com from nothing. That path needs a business licence, bank verification, and an inspection, and no number substitutes for those. It is also not for evading a ban: AliExpress links accounts by device and payment instrument, and a fresh number on the same phone and card is caught quickly. For a Chinese-side account that pairs with Alibaba, such as WeChat for supplier chat, see /blog/temp-number-for-wechat.
Conclusion
AliExpress and Alibaba.com both put an SMS step between you and a usable account, and a private mobile-range activation from TempNumber.me passes it in almost any major country for AliExpress and in the US, UK, Germany, or Netherlands for Alibaba.com buyer accounts. The specific hazard is recycled numbers, which Alibaba Group recognises and attaches to old accounts, so avoid shared inbox numbers and take a fresh private activation. Supplier verification on Alibaba.com is a document process the SMS step does not touch. Browse available numbers at /countries or view pricing at /pricing.
