A Nanjing Company Website Has Passed ICP Filing—Does Public Security Network Filing Still Need to Be Submitted Separately?

After a Nanjing company website has passed ICP filing and can open normally, according to platform rules and local public security cyber security requirements, it usually still needs to add a public security network filing on the National Internet Security Management Service Platform. It is not a replacement for ICP filing but a separate line: one falls under the communications administration, and the other falls under the local public security cyber security department. Based on 2026 Nanjing local website delivery experience, this usually does not get stuck on cost; it gets stuck because no one fills it in and no one follows up. The earlier it is added, the less likely the company will be pressed for it when running ads or going through partner verification.

ICP filing and public security network filing: where Nanjing companies often confuse them

Many Nanjing companies understand filing as one thing because ICP filing is completed end-to-end in the backend of access providers such as Alibaba Cloud and Tencent Cloud, so they feel the materials have already been submitted. But ICP filing addresses whether a website can provide public access, while public security network filing addresses the website operator reporting to the local public security cyber security department. The systems filled in, the reviewers, and the numbers obtained are all different.

In Nanjing delivery experience, ICP filing is commonly submitted with help from the access provider, with the legal representative cooperating with face verification and stamping. Under Jiangsu practice, the cycle is typically 7 to 20 working days. Public security network filing, however, mostly requires the company to register an account and fill in each item itself, and the website responsible person's mobile number must be reachable for return calls. This is the step most often missed.

• Authority and portal: ICP filing goes through the MIIT filing system, assisted by the access provider; public security network filing goes through the National Internet Security Management Service Platform.
• Who handles it: The access provider can handle most of ICP filing; public security network filing is commonly submitted by the company or the website responsible person.
• Cost: ICP filing is usually bundled with the server or hosting space and is not charged separately; the public security network filing platform itself is free, and using an agency commonly falls in an experience range of a few hundred RMB in service fees.
• Timeline: ICP filing in Jiangsu is typically 7 to 20 working days; public security network filing review is typically 3 to 10 working days, sometimes longer in individual cases. Both are experience ranges.
• Display location: The ICP filing number is usually placed in the website footer with a link to the MIIT system; the public security filing number is placed in the footer with a link to beian.gov.cn.

On the delivery ground: where Nanjing company websites commonly get stuck when adding public security filing

In Nanjing projects, a common situation is this: the client's budget is focused on a display-type official website, requiring launch in two to three weeks, and the delivery checklist emphasizes columns, mobile, and backend. The website launches on schedule, and ICP filing also comes through smoothly, but public security network filing is not scheduled into any milestone. The constraints are that the legal representative is short on time, proof of office address cannot be gathered at short notice, and the website responsible person changes phone number midway. In practice, if the domain real-name entity, business license address, and website responsible person contact are checked at delivery, the chance of completing it in one pass is much higher.

If it is delayed until the company is running search ads, applying for platform enterprise verification, or going through due diligence with a major client, the common cost is taking 1 to 2 weeks to go through it again, and rejected materials must be resubmitted. It is not that the website cannot open without it, but it can block business milestones, especially for Nanjing companies doing B2B business, where the other party's compliance department sometimes checks it as a matter of course. Based on common practice in 2026, writing the filing checklist into launch milestones at delivery is less trouble than adding it two months after launch.

• Check the entity first: Domain real-name, ICP filing entity, and business license name should be consistent as much as possible; otherwise, public security filing is prone to mismatches when filled in.
• Then check the contact: The website responsible person's mobile number must be reachable. An unchanged number after switching is a common reason for rejection.
• Prepare address proof: Some cases require office address or lease materials; asking clearly in advance can save a trip.
• Add after launch: Sites already online can also submit later; commonly the website does not need to be taken offline.

Compliance sequence before and after a Nanjing site goes live: follow this checklist

Filing matters easily become chaotic because domain, ICP, public security filing, and Classified Protection are mixed at one point in time. A more reliable approach is to sequence them by before and after launch, with each step solving only one problem. If the previous link is not aligned, do not rush to fill in the next one.

1. Align domain real-name and entity: The registrant should preferably be under the company name and consistent with the business license name.
2. ICP filing: Submit with access provider assistance; in Jiangsu it is typically 7 to 20 working days, so leave enough buffer.
3. Launch the website and complete basic display: Place the ICP filing number in the footer and link it to the MIIT filing system.
4. Public security network filing: According to platform rules, commonly submit within 30 days after the website goes online; refer to platform prompts for specifics.
5. Systems involving membership, transactions, or personal information: Separately assess whether Classified Protection is needed. Ordinary display-type official websites usually do not involve it.

The reason for this order is that the first two steps determine whether the website can legally provide public access, the third determines whether information display is complete, the fourth is local reporting, and the fifth is deeper security compliance. A common consequence of reversing the order is repeated material submissions, with time spent waiting for review.

Submit it yourself or hand it to a Nanjing website company: how to choose

Public security network filing can be submitted by the company itself on the platform. The actions are not complicated, but wrong entries, missing items, and unreachable contacts for return calls all delay the process. Whether to hand it off mainly depends on whether the company has someone who can steadily monitor review calls.

• Submit yourself: Suitable for Nanjing companies with administrative or HR staff who can follow up continuously. The platform is free, commonly 3 to 10 working days, and the variable is having someone answer return calls.
• Get help from a website company or agency: Suitable for companies with no one internally managing it, or companies handling both ICP and public security filing at the same time; common service fees fall in the few-hundred-RMB range. The benefit is familiarity with the process and a higher chance of passing materials in one go.
• When you do not need to find someone: If the website is only a short-term campaign page going offline after a few weeks, and it will not run ads or undergo platform verification, you can first focus on website content and indexing.

According to Nanjing local project delivery habits, we usually include public security filing in the launch checklist and hand it over together, but we do not package it as a must-buy item, because whether to add it is directly related to the company's business purpose.

Applicable scenarios and boundaries

Those who need to seriously add public security network filing are usually enterprise official websites that are publicly accessible and will operate long term, especially companies that will run search or feed ads, participate in platform enterprise verification, or engage with major clients or government-related cooperation. Websites with message forms or that collect customer information should also add it as early as possible.

• Suitable to add: Enterprise official websites, marketing sites with forms or consultation entry points, and sites that need to prove compliance identity externally.
• Can be deferred: Internally used systems, demo sites not open to the public, and campaign one-pagers going offline soon.
• Not necessarily applicable: Sites with servers outside mainland China and no ICP filing do not follow this process, but they have separate access and compliance issues to review.

The boundary can be summed up in one sentence: If a website is open to the public long term and is used to win business or pass platform verification, public security network filing is worth putting on the launch checklist; for purely internal or short-term display sites, you can defer spending this effort.

FAQ

If a Nanjing enterprise official website does not do public security network filing, will the website be shut down directly?

Commonly it will not be shut down immediately because of this item; it affects ad account opening, platform verification, and partner due diligence more. However, if local requirements say filing is required and it is not done, there is a possibility of being reminded to rectify. It is advisable to judge priority by use case.

Does public security filing require the legal representative to go to a Nanjing police station in person?

In most cases, no on-site visit is needed. Online submission on the National Internet Security Management Service Platform is sufficient, and review is completed by the local public security cyber security department. Some material verification may involve phone return calls, so keeping the website responsible person's phone reachable is more important.

If a website has been online for a long time and only then adds public security network filing, will it be penalized?

The supplementary filing channel is commonly open, and the key is to fill in the entity, domain, and responsible person information accurately. Whether it involves penalties depends on local requirements and the nature of the website content. Dragging it out for a long time is worse than completing it as early as possible.

If we hire a Nanjing website company to build the official website, can they submit public security filing for us?

Many website companies or agencies can help organize materials and fill in the platform on behalf. However, key steps such as legal representative information and website responsible person return calls still require company cooperation. Confirm the service boundary before commissioning and do not assume it is all-inclusive.

If the company moves to another district in Nanjing, should public security filing information be changed?

When the entity address, office address, or responsible person changes, it is commonly recommended to make a change on the platform to avoid mismatches with the business license and ICP filing information. The change itself is not complicated; delaying it often creates higher explanation costs during verification.

If the official website has just been completed and you are preparing to run ads or engage major clients, it is advisable to first align domain real-name, ICP filing, and public security network filing, then discuss keywords and content updates. If the website is only for internal use or short-term display, there is no need to force supplementary filing just to be complete; putting budget into pages customers can see is more practical. For specific review standards, refer to the latest prompts from the local public security cyber security department and the platform.
