The time it takes for tradelines to post can vary depending on the specific trade line company and the credit reporting agency involved. It can take a few weeks to a few months for the tradelines to appear on your credit report. Once you have purchased personal tradelines, the provider will contact the credit card company or lender. They will request that you become an authorized user. The credit card issuer or lender will then update the account information with the major credit bureaus. The reporting speed can depend on several factors, including the reporting practices and the reporting cycle of the credit reporting agency or lender. Some trade line providers offer expedited reporting. It can help speed up the process.
