How to Choose an ICP Sponsor for Your Domain

You read the ICP filing guide. You worked out you need a sponsor — a licensed mainland host whose IDC (Internet Data Center) license is on file with MIIT (the Ministry of Industry and Information Technology, the regulator that runs the filing system). Now you have a shortlist of five companies who all quoted you between RMB 1,200 and RMB 9,800 for what looks like the same thing. The cheap one says three weeks. The expensive one says nothing at all about timeline. None of them volunteers what happens if your filing is rejected.

This article is the question list you can paste into your next sponsor email. It is written for the foreign founder who has never filed before and does not want to spend a quarter learning by failure. The decision you make here decides whether your filing stalls in week 2 or in week 12 — and whether your domain is portable to a different sponsor a year from now without going dark.

An ICP sponsor does four things for you, in this order. First, it submits your filing through the MIIT 备案 (record-filing) system on behalf of the host they operate — the filing is tied to the IP address pool the sponsor controls, which is why you cannot keep your filing if you move hosts. Second, it runs the real-name verification of your 法定代表人 (legal representative) and the entity that owns the domain. Third, it manages the 30-day PSB (Public Security Bureau) sub-filing clock that starts the day MIIT approves you. Fourth, it handles the annual review every November-to-January window when the provincial communications administration spot-checks records.

Notice what is not on that list. Your sponsor does not own your domain. Your sponsor does not own your site content. Your sponsor cannot pull your filing without giving you a window to migrate. But the sponsor is the only party with login credentials to the MIIT portal where your filing lives, so functionally they hold the keys until you transfer them.

This is why "who is the sponsor" is a bigger question than "how cheap is the price." If the sponsor's IDC license is revoked, your filing dies with it. If the sponsor decides to stop serving foreign accounts, your domain can be parked until you find a replacement and re-file from scratch. The relationship is more landlord-and-tenant than vendor-and-buyer.

The honest fee band in 2026 for a foreign-owned single-domain 备案 (filing) sponsorship is RMB 1,800–4,500 one-time for the filing service plus RMB 600–1,800/yr for ongoing record maintenance and annual review handling. Anything under RMB 1,200 means one of three things is being skipped:

• Document translation review. Cheap sponsors submit your apostilled certificate of incorporation untranslated, get rejected, and you eat the resubmission cycle.
• Real-name verification handholding. If your 法定代表人 is offshore, the verification call requires a Chinese-mainland phone number that the sponsor staffs. The cheap ones use a shared number that voicemails out — your application sits in queue.
• Province-match diligence. The sponsor's IDC license is regional. Some provinces refuse filings from sponsors licensed elsewhere even when the same servers physically host both. A cheap sponsor will lodge the filing and tell you afterwards.

The high end of the band — above RMB 6,000 — usually buys you bilingual account management, named contact, and an SLA on resubmission turnaround. For a single-domain marketing site that is overkill. For a SaaS that needs uptime continuity across an entity change, it pays for itself the first time something breaks.

Send these five questions verbatim to every sponsor in your shortlist. Answers that arrive in 24 hours, in writing, with specifics — that is your sponsor. Answers that come back as "contact us by phone" or "depends on your case" — strike them off.

1. What province is your IDC license registered in, and what is the license number? A real sponsor states "Zhejiang 浙B2-XXXXXXXX" or equivalent without hesitation. If they hedge, your filing will sit in province-mismatch limbo.
2. What is your average resubmission rate for foreign-entity filings in the last 12 months? Honest answer is 12-25%. If they say "zero," they are lying. If they say "depends," they do not measure.
3. What is your written process if MIIT rejects on first submission? The correct answer names the rejection reason categories (document quality, content sample, scope mismatch) and gives an expected fix-and-resubmit window per category.
4. If I want to migrate this filing to another sponsor in 18 months, what do you charge to release? A reasonable release fee is RMB 300-800. A sponsor that says "non-transferable" is lying — every filing is transferable; they just want to bill you for the entire next year before letting you go.
5. Who is my account contact, and what is their direct WeChat ID? A real sponsor names a person. A bad sponsor sends you to a queue. Foreign-account filings rejected at the document-quality stage need a human triage call within 48 hours or you lose a week.

This happens more often than the industry advertises. The 2022 Henan IDC consolidation pulled licenses on roughly 40 small sponsors over six months. The 2024 Sichuan compliance sweep was smaller but caught two foreign-friendly mid-sized hosts. When a sponsor loses its IDC license, every filing tied to that license enters a 30-day cure window during which the affected sites are flagged but not yet blocked.

In practice you get notified by SMS to the legal rep's Chinese mobile number — which is why having a real, monitored number on file matters. From the SMS date you have those 30 days to find a replacement sponsor, file a transfer request, and have the receiving sponsor's IDC license validated by the provincial communications administration. Miss the window and the filing is suspended; the site is blocked at the carrier level; recovery means filing from scratch.

Mitigation: pick a sponsor whose IDC license has been continuously active for at least three years, whose parent company is a publicly traded cloud provider (think the big-three mainland cloud operators or a regulated telecom subsidiary), and whose foreign-entity book of business is at least a few hundred filings. Boutique sponsors below that scale fail more often.

The clean way to switch sponsors is the dual-sponsor 7-12 day overlap. You sign with the receiving sponsor, give them the documents they need (entity proof, current filing record number, legal rep ID, domain WHOIS), they file a transfer-in request through MIIT, you authorize the release at your current sponsor, and the receiving sponsor takes over the record. The site stays live the entire time because both sponsors briefly hold the filing in parallel.

Costs: RMB 800-1,500 for the receiving sponsor's transfer setup, plus the release fee your current sponsor charges. Avoid the temptation to cancel at the current sponsor first and then re-file — that pattern looks to MIIT like a lapsed filing and triggers the 30-day cure clock unnecessarily.

Can I run my site without a sponsor for a few months while I shop around?

Yes if the site is hosted offshore. The moment you move hosting to a mainland IP without an active filing, you have between hours and days before the carrier blocks the IP for the affected domain. Shop sponsors before you migrate hosting, not after.

Does the sponsor need to be in the same province as my WFOE?

Not legally, but mismatched-province filings get extra scrutiny and a noticeably higher first-pass rejection rate. If your WFOE is in Shanghai, prefer a Shanghai or pan-eastern-China IDC license. The province-match rule is enforced unevenly but consistently enough to weight your choice.

What if my sponsor refuses to release my filing when I want to switch?

Escalate to the provincial communications administration with a written transfer request, your release-fee payment receipt, and the receiving sponsor's IDC license number. Forced releases are processed within 30 business days. In practice the threat of escalation is enough — sponsors do not want a documented complaint on file.

Is there a sponsor I can use without a WFOE?

Only for very narrow cross-border arrangements where a sponsor takes legal-entity responsibility for your filing. These exist but they are expensive (RMB 8,000-15,000/yr), restrict content categories, and put a third party on the filing record. For most foreign brands a WFOE-held filing is cleaner.
