Today, post offices deliver more money than mail. They therefore represent a prominent channel for the provision of remittances and financial services to the world's underserved rural areas. With the aim of supporting postal networks in fulfilling their potential in the national remittance market, this set of three working papers explores ways to maximize the impact of remittances delivered through post offices. They provide lessons learned, stemming from the experience of the African Postal Financial Services Initiative and other past and ongoing initiatives, and provide guidance on how to expand their outreach at the last mile, enhance their impact through partnership building and improve customer centricity in order to reach underserved clients in rural areas.
