A blockchain includes multiple levels of accounts used to maintain e-bill number segments. An e-bill number application transaction published to the blockchain is received, where the e-bill number application transaction includes an account identifier of an account of a number applicant; allocating one or more e-bill numbers to the number applicant from an e-bill number segment maintained in an upper-level account corresponding to the account of the number applicant in response to the e-bill number application transaction; and adding the one or more e-bill numbers allocated to the number applicant to the account of the number applicant for maintenance.
