The leakage of the house contract number is not serious, because the contract number is actually just the order of a contract. It only represents a number. It is not a big deal whether it is leaked or not. The key is that the original contract cannot be lost. You should pay attention to it. A copy of the contract is also very important, as some people often use copies to defraud. Each house purchase contract is numbered, and it is a unique number, so there will be no duplication. The number of a house purchase contract is generally eight digits, and the contract code is a barcode that needs to be scanned by a scanner at the real estate transaction center. Don't underestimate this number, it is a certificate that can prove the authenticity of the contract. Moreover, the real estate contract number can only be found on the internal network of the housing management department.
