I am a salesman of a foreign trade company. I just took over an agency export order last month, and the cooperating agency company is based in Shanghai.
Now the overseas customer is urging for the agent export number for customs clearance. I have checked the entrustment agreement signed with the agency, the bill of lading provided by the freight forwarder, and the declaration receipt from the customs broker, but failed to find this number.
I asked the contact person of the agency yesterday, and they said it is in the filing records of the Electronic Port, but I logged into the China Electronic Port and searched for a long time but could not find the corresponding entry, and I am afraid that wrong operation will delay the matter. Now the customer has urged twice, and I have no clue at all. I want to know where to find the agent export number, and whether there is a quick inquiry method.

The agent export number is the core number used to identify the entrustment relationship and declaration information in the agency export business，and its inquiry path can be checked one by one according to the business link: First，the most direct carrier is the "Entrustment Agreement for Agency Export of Goods" signed by both parties. A formal agreement will clearly indicate the agency filing number，which is commonly known as the agent export number.
Second，you can log in to the China Electronic Port system upgraded in 2026，and query in the "Agency Customs Declaration Entrustment Filing" module. The system has added a one-click export function，which allows you to directly obtain the filing number. If you cannot find it through the Electronic Port，you can contact the agency to obtain its entrustment filing receipt from the customs，which will also mark the agent export number.
In addition，the "remarks column" of the official customs declaration form will also be marked with the agent export number. If the customs declaration has been completed，you can download the receipt through the customs broker or the customs declaration query module of the Electronic Port for checking. If you still cannot find it，you can contact the local customs clearance service window，provide the unified social credit codes of the entrusting party and the agency，and apply for retrieving the filing information.
It should be noted that the customs has realized the linkage verification between the agent export number and the customs declaration number in 2026. If this number is missing，normal declaration cannot be completed. Therefore，you must confirm the number and keep the documents in the entrustment link to avoid subsequent problems in customs clearance or tax refund.

The core carriers of the agent export number are concentrated in the relevant documents of the customs declaration link. If the conventional inquiry is fruitless, you can first check the electronic filing data of the customs declaration entrustment. The agency customs declaration entrustment system of the customs realized full-process electronization in 2026. After both parties to the entrustment complete the online signing, the system will automatically generate a unique agency filing number, which is the agent export number.
If you have not kept the signing record, you can retrieve the entrustment filing file through the internal operation system of the customs broker, and the system will automatically synchronize this number. In addition, if the customs declaration has been completed, the agent export number will be marked next to the "filing number of the operating unit" column of the customs declaration form. You can download the official receipt through the customs declaration query module of the Electronic Port for checking.
It should be noted that some agencies will confuse the agent export number with their own customs broker number, so when querying, you need to clearly request the "exclusive number for entrustment agency filing" instead of the self-operated customs declaration number of the agency. In case of system data delay, you can contact the customs clearance management department to apply for manual verification, and you can generally get the accurate number within 1-2 working days.
Meanwhile, under the "integrated customs clearance" mode implemented in 2026, the agency filing data of ports across the country has been interconnected. You do not need to limit the query to the system of Shanghai Port, and you can submit a verification application through the national unified customs service platform.

You can also find the agent export number from the documents of the logistics link. First, the "consignor remarks column" of the marine bill of lading or air waybill issued by the freight forwarder usually marks the agent export number, which is the filing information entered by the agency synchronously when booking the shipping space.
If the bill of lading does not show this number, you can contact the freight forwarder to obtain the booking confirmation, and the booking system will keep the filing number of the entrustment agency. Second, the dock receipt after the goods are shipped also contains the relevant field of the agent export number. The dock receipt is one of the core documents for customs declaration, and you can apply to the freight forwarder or the dock for the electronic version.
In addition, the international logistics platform realized document data linkage in 2026. If you entrust the booking through a cross-border logistics platform, you can directly check the agent export number in the "entrustment order details" of the platform.
It should be noted that some freight forwarders will hide the agent export number in the additional clauses of the bill of lading to simplify the operation, so you need to carefully check the back clauses or attachment parts of the bill of lading. If you still cannot find it, you can ask the agency to provide its booking agreement with the shipping company, which will clearly mark the filing number of the agency export.

First, the foreign exchange receipt voucher of the agency will mark the filing number of the agency export, which is the necessary information for compliance review of foreign exchange receipt and payment.

It should be noted that the agent export number is the core element of compliance review for cross-border foreign exchange receipt and payment, and the absence of this number will make it impossible to complete the normal foreign exchange receipt verification and write-off.

From the perspective of legal compliance, the agent export number is one of the core clauses of the entrustment agency agreement, so it will be clearly marked in the contract signed by both parties. First, you can recheck the "Entrustment Agency Export Agreement" signed with the agency, and the "entrustment matters" column of the agreement will clearly mark the agent export number, which is the core right and obligation identifier agreed by both parties.
Second, in the exchange emails and chat records between the two parties, if the agency has confirmed the completion of the entrustment filing, it will usually send the information of the agent export number synchronously, and you can query through the historical communication records.
It should be noted that if the agency does not mark the agent export number in the agreement, it is a lack of contract clauses, and you can require the agency to sign a supplementary agreement to clearly mark the number. In addition, the "Compliance Guidelines for Cross-border Trade Contracts" implemented in 2026 clearly requires that the agency export contract must include the agent export number.
If your contract does not include this clause, you can contact a professional legal officer to assist in the improvement to avoid subsequent legal risks. Meanwhile, if the communication records between you and the agency contain the confirmation information of the agent export number, the records can also be used as compliance evidence.

It should be noted that the agent export number is the core verification element of customs inspection, and the absence of this number will make the goods unable to pass the customs clearance normally, and may even be temporarily detained.
