Finding it by reading two long documents, or by comparing a PDF to a web page, is slow and easy to get wrong, and the comment window will not wait for you. See it in the product ## The difference between a proposed rule and the final rule This is a real comparison of two versions of a federal rule, published October 26, 2026. USLege found 22 changes. Three are shown. FCC, Enhancing the Ability of Consumers To Control the Robocalls, 91 FR 67214Live data **22** changes**+193** lines added**\-141** lines removedCompared: Proposed rule to Final rule ACTION Proposed rule. Final rule. DATES Comments are due on or before November 25, 2026, and reply comments are due on or before December 28, 2026. Effective November 25, 2026. SUMMARY The Commission seeks comment on measures to ensure that the Telephone Consumer Protection Act (TCPA) rules that govern robocalls continue to evolve with changes in technology and industry practices. The Federal Communications Commission (Commission) modifies rules to ensure that consumers can revoke consent for robocalls they no longer wish to receive while continuing to receive those they still want. Real text from the Federal Register, shortened to three of 22 changes. Most rules have a single version on file; a redline appears when a rule has two. How it works ## From the rule to the redline in three steps STEP 1 ### Find the rule Search by agency, code section, stage, comment deadline, or the words inside the rule itself. STEP 2 ### Pick two versions Choose an older and a newer version, or leave off the newer one to compare against the current text. STEP 3 ### Read the redline See each change in document order, with the unchanged lines around it for context. Before and after ## Read the change, not the whole rule The job Before With USLege Spotting what changed Read two long documents side by side A redline in document order, with context A PDF against a web page Fight the formatting differences Compared as text, so formatting is ignored Watching a deadline Check the register by hand Filter rules by comment deadline What's included ## A redline you can trust ◆ ### Sentence-level comparison Changes are shown in document order with a couple of unchanged lines around each one, so you see what moved in context. ◆ ### HTML, text, and PDF Versions compare as text, so a web notice and a PDF of the same wording show as identical instead of flagging formatting noise. ◆ ### Compare to the current text Leave off the newer version and USLege compares your older version against what is in force now. ◆ ### The full life of a rule Proposed, comment open, final, adopted, emergency, effective, withdrawn, or repeal, with the comment window dates and the citation. ◆ ### Search inside the rules Find every rule that actually says something, not just the ones whose titles mention it, by searching the text of the rule itself. ◆ ### Filter by agency and code section Narrow by issuing agency, code division or section, stage, or comment deadline. ◆ ### State and federal rules Agency rulemaking from 49 states and the federal government, in one place. ◆ ### Honest about what it cannot read If a version is a scanned image that cannot be read, USLege says so instead of guessing at the change.

Who it is for ## For teams that answer to the rulebook [Law firms](/for/law-firms)[Corporations](/for/corporations)[Government agencies](/for/government-agencies)[Trade associations](/for/trade-associations) Questions ## What do teams ask about rule version comparison? How do I compare two versions of an agency rule? + Open the rule, choose the older version and the newer version, or compare against the current text. USLege returns the differences in document order with surrounding context. Can it compare a PDF to a web version? + Yes. HTML, plain text, and PDF versions are compared as text, so the same wording in two formats shows as unchanged. For long PDFs, the first 150 pages are compared. Does every rule have a redline? + A redline is available when more than one version of the rule is on file. A rule with a single version shows its full text and its lifecycle. Which states are covered? + Agency rules are tracked for 49 states and the federal government. Coverage of formal state register notices is more limited, so ask about the states you track. Can I ask for a redline from Claude or ChatGPT? + Yes. Through USLege MCP, ask what changed between the proposed and adopted versions of a rule, and the comparison comes back in the conversation.
