No — uninvited door-to-door sales are prohibited under Egyptian consumer law. Article 16 explicitly forbids suppliers from visiting residential units to offer or sell products without a prior and explicit request from the consumer. This means a salesperson cannot legally knock on your door or approach you at home to pitch products unless you have specifically invited them to do so.
This protection is especially relevant for expats who may be targeted as presumed high-value customers. If someone shows up uninvited at your home trying to sell goods or services, you are within your rights to refuse and to report the incident to the Consumer Protection Agency (CPA).
If you do agree to a purchase during an unsolicited visit (for example, before realizing your rights), remember that you still retain your 14-day return right under Article 17. Always document unsolicited sales visits if you intend to file a complaint — note the date, time, company name, and what was being sold.
