SMS OTP delivery to mainland China
Sending login, sign-up or account recovery codes to mainland China mobile numbers (+86)? Tell Bumpcube what you need to send. We’ll review your use case and explain what you need for registration.
Before you send
Why delivery can fail
A message can be blocked if its brand name or wording differs from what was approved. The brand name in brackets is called the sender signature. The approved wording is called the message template.
What a China OTP looks like
【示例品牌】您的验证码是 {code}。
The brand name and wording stay the same. The {code} placeholder is replaced with a new verification code for each request. Bumpcube can help you prepare the draft for review.

Step 1
Tell us what you need to send
What the code is for
Tell us what triggers the code, such as sign-in or account recovery. If you already have an SMS template, share it with the code replaced by a placeholder.
Expected SMS volume
Tell us roughly how many verification texts you expect to send each month.
Step 2
Prepare for registration with Bumpcube
Choose your sender signature
Use Chinese characters only in your sender signature. Leave out digits, spaces and symbols. Choose a name you can support with company, trademark or ICP filing records. Bumpcube will confirm the required length, bracket format and supporting documents.
Prepare your OTP template
Draft a short message in Simplified Chinese with a placeholder for the code. Leave out links, contact details and IP addresses. Once approved, keep the wording, spacing and punctuation as registered. Bumpcube will advise on any restrictions for your industry.
Prepare your registration documents
For registration, prepare your mainland China business licence and the Chinese national ID and mobile number of your authorised employee in mainland China. If you use a trademark as your sender signature instead of your registered business name, you’ll also need the trademark certificate. Bumpcube will guide you through the paperwork and explain how to submit it securely.
Step 3
Test delivery before launch
Once the sender and template are approved, we’ll help you plan a test with mainland China mobile numbers. Check how quickly codes arrive and whether users can complete verification before increasing volume.
Frequently asked questions
Sending OTPs to +86 numbers
Can I send China SMS OTPs from an overseas company?
Eligibility depends on the sending company and use case. Tell Bumpcube where your company is registered and what the codes are for. We’ll review eligibility and explain what documents you may need.
Can we send our existing English OTP template?
Start with Simplified Chinese. English-only messages and signatures may be filtered or rejected. Share your draft with Bumpcube and we’ll advise on the language, signature format and code placeholder.
What if we change the wording or brand?
Send the revised wording or brand name to Bumpcube before using it. Changes to fixed text, signature or variable placement may require a new approval.
What should we check when a code doesn’t arrive?
If your China OTPs aren’t arriving, tell Bumpcube which networks are affected and share any delivery errors. We can help review the sender setup, template and delivery results.
